Why first copy out time matters more than pages per minute

Stand at any office copier and watch what happens for the next hour. Most users walk up, send a one or two page document, wait for it, take their pages, and leave. The hour might rack up 80 or 100 individual copy and print operations, of which maybe two run beyond ten pages. The headline pages per minute number on the spec sheet measures sustained throughput on long jobs that almost no one prints. The first copy out time number measures how long the user actually waits, and that wait is what users experience as the speed of the machine.

A 70 page per minute machine with 9 second first copy out time feels slower in daily use than a 35 page per minute machine with 4 second first copy out time. Most office workloads sit on the side of the comparison where short jobs dominate.

What first copy out time actually measures

First copy out time, abbreviated FCOT, is the elapsed time from the moment the user presses start on the operator panel to the moment the first physical sheet emerges into the output tray. Manufacturers measure FCOT under controlled conditions defined in ISO/IEC 17629, the standard for first page measurements. The test starts the clock at the press of the start button and stops it at the leading edge of the first page reaching the catch tray.

FCOT is reported separately for several conditions. From ready state, where the machine is warm and waiting. From sleep state, where the machine has powered down components to save energy. From cold start, where the machine has just been switched on. The three numbers can differ by a factor of three or more on the same machine, with cold start being the slowest and ready state being the fastest. Spec sheets typically advertise the ready state number as the headline FCOT, with the other two figures listed in smaller print. The deeper read on the chassis components that contribute to each of these timing measurements is at How a photocopier actually works in six clear steps.

What contributes to FCOT

Three internal stages drive most of the FCOT figure. Fuser warm up adds 0 to 8 seconds depending on whether the fuser is at temperature or recovering from a sleep cycle. Rasterization adds 1 to 4 seconds depending on document complexity and controller speed. Mechanical processing, where the paper feeds through the imaging path and reaches the fuser, adds 2 to 4 seconds at typical speeds.

Adding the three stages gives a typical FCOT of 4 to 12 seconds from ready state. Cold start adds 30 to 60 seconds of fuser warm up, pushing the total to roughly 35 to 70 seconds for the first page. Sleep recovery sits in between, with modern induction heating fusers reaching ready state in 5 to 15 seconds from sleep. The relationship between fuser warm up time and overall machine timing connects to the broader question of how the chassis manages standby and sleep modes, sketched out at A guided tour of every part inside a modern office copier.

4 to 12 secondsThe typical FCOT range from ready state on modern office MFPs. Cold start adds 30 to 60 seconds. Sleep recovery falls somewhere between depending on the fuser technology.

Why fuser warm up dominates the cold start case. The fuser uses heated rollers to melt toner into paper, requiring temperatures between 175 and 195 degrees Celsius. From cold the fuser has to warm up the entire roller mass, a process that takes 30 seconds or more on traditional halogen lamp fusers. Modern induction heating designs reach temperature faster because the heat is generated directly in the roller surface rather than transferred through the air gap from a lamp. Different brands implement different fuser technologies, with the choice partly driving the FCOT advertised on the spec sheet.

The arithmetic of short jobs

For a one page job, the total time the user waits equals FCOT plus zero, since the first page is the entire job. A 70 page per minute machine with 9 second FCOT takes 9 seconds for a one page job. A 35 page per minute machine with 4 second FCOT takes 4 seconds for the same job. The faster machine on continuous throughput is the slower machine on real office workflow.

For a five page job, the math starts to favor the higher PPM machine but only modestly. The 70 ppm 9 second FCOT machine takes 9 seconds for the first page plus 60 divided by 70 times 4 equals roughly 3.4 seconds for the remaining four pages, totaling 12.4 seconds. The 35 ppm 4 second FCOT machine takes 4 seconds for the first page plus 60 divided by 35 times 4 equals roughly 6.9 seconds for the remaining four pages, totaling 10.9 seconds. The slower nominal machine still wins on a five page job.

The crossover point where higher PPM begins to beat lower FCOT depends on the specific machines being compared. For the 70 ppm versus 35 ppm comparison, the crossover sits around 11 to 13 page jobs. Below that page count, the lower FCOT machine produces output faster. Above it, the higher PPM machine pulls ahead. Where the office sits on the page count distribution determines which spec matters more for daily user experience. The case for matching equipment to workload, where these short job versus long job patterns inform the choice, sits at How to tell whether you need an office class copier or a production class one.

What the office workload actually looks like

Pulling print logs from a typical Spanish SMB office reveals a long tail distribution. Roughly 60 percent of jobs run 1 to 3 pages. Another 25 percent run 4 to 10 pages. The remaining 15 percent run 11 pages or more, with a handful of jobs each month exceeding 100 pages. The arithmetic of who waits for what depends entirely on this shape.

For 60 percent of jobs the office runs, the user is waiting for the first page and then immediately receiving subsequent pages without further delay. The FCOT figure dominates the wait time entirely. For another 25 percent of jobs the user waits a few extra seconds after the first page for the rest, but the FCOT still represents most of the perceived delay. For the long tail of larger jobs, the PPM number takes over, but those jobs are typically batch work where the user is not standing at the printer waiting in any case.

An office optimized around long batch jobs has different needs than an office optimized around short interactive jobs. Print shops fall into the first category, with most jobs being multi hundred page production runs and PPM dominating the time budget. SMB offices fall into the second category, with most jobs being short ad hoc prints and FCOT dominating. Where this maps to the segment classification system shows up in the difference between Segment 6 production equipment optimized for sustained throughput and Segment 3 office equipment optimized for everyday user response. The mapping is at What the industry copier segments from one through six actually mean for you.

The Konica Minolta bizhub C360i and Kyocera TASKalfa 4054ci both achieve FCOT around 4.5 seconds in ready state and 9 seconds from sleep, the fastest figures in the comparison group. The HP Color LaserJet MFP M683f comes in at the slow end with 10.5 seconds FCOT in ready state, more than twice the Konica Minolta. For a workload heavy on short jobs, the Konica Minolta delivers a meaningfully better user experience despite all six machines sitting in roughly the same speed band on continuous PPM.

The everyday distinction between FCOT and PPM is one of the parts of the spec sheet that gets less attention than it deserves during dealer pitches. Buyers comparing three quotes that all show similar PPM numbers and similar prices sometimes find that the FCOT spread between them differs by 50 percent or more. Asking the dealer specifically for the FCOT in ready state and the FCOT from sleep, and writing both numbers into the proposal comparison spreadsheet, shifts the conversation toward what users actually experience.

Sleep mode and FCOT trade offs

Office MFPs save energy by entering low power sleep modes when idle. The sleep state can drop power consumption from 80 to 200 watts active down to 1 to 5 watts. Energy savings across a year for an office of 25 staff with a single MFP can reach 200 to 400 euros depending on tariff and idle time. The trade off is that recovering from sleep takes longer than starting from ready state, increasing FCOT for the first job after a quiet period.

Configuring the sleep timeout balances energy savings against user experience. A short timeout of 5 minutes maximizes energy savings but means most users hit a sleep recovery delay on every print job. A long timeout of 60 minutes keeps the machine ready during business hours but reduces energy savings. The default on most machines sits at 15 minutes, which works for most offices but can be adjusted up or down based on usage patterns. The deeper read on warm up time and sleep recovery as separate measurements is at Warm up time and sleep recovery time as specs you might be misreading, the next entry in this series.

For offices where users frequently hit sleep recovery delays, configuring scheduled wake up periods removes the delay during peak hours. Most modern MFPs support wake schedules where the machine forces itself awake at specific times of day, ready for the first user. A scheduled wake at 8.30 AM keeps the office MFP in ready state through the busy morning hours, dropping into sleep only at lunch and after hours.

What FCOT does not capture

FCOT measures only the first page. It does not capture queueing delays from other users, network transmission time for large files, or rasterization time for complex documents. A user sending a 50 megabyte PDF over a slow network connection might wait an extra 5 to 15 seconds for the file to upload before FCOT even starts. The total user experience time is FCOT plus all the upstream delays that happen before the print job reaches the chassis.

Some manufacturers report time to first page (TTFP), which extends FCOT to include rasterization time for a representative document. TTFP is often a more useful number because it accounts for the controller processing burden that pure FCOT measurements ignore. Reading both FCOT and TTFP, where both are listed, gives a fuller picture of how the machine handles real workloads.

The everyday distinction between machines that look similar on FCOT but differ on TTFP traces back to the controller hardware. A faster controller with more RAM rasterizes complex pages quicker, narrowing the gap between FCOT and TTFP. A slower controller stretches the gap. Where the controller architecture sits within the larger chassis story, the deeper read is at The simplest possible explanation of what a multifunction printer does, where the controller is described as the brain of the MFP.

How to weight FCOT and PPM in a buying decision

Pull the print log from the existing fleet to estimate the page count distribution. If 60 percent or more of jobs run under 5 pages, FCOT matters more than PPM and should drive the comparison. If most jobs run over 20 pages, PPM matters more and FCOT becomes a secondary factor. For mixed workloads, weighting FCOT and PPM equally and computing a combined score for each candidate machine produces a usable ranking.

The combined score formula works as follows. Take the average job page count from the print log. Compute the total time per average job as FCOT plus the page count divided by PPM, multiplied by 60 to convert to seconds. The lower number wins. Two machines with different FCOT and PPM specs can be compared on this single number rather than on each spec separately.

For an office with average 4 page jobs, a 70 ppm 9 second FCOT machine produces 9 plus 60 divided by 70 times 3 equals 11.6 seconds total per job. A 35 ppm 4 second FCOT machine produces 4 plus 60 divided by 35 times 3 equals 9.1 seconds total per job. The slower nominal machine wins on this workload by 22 percent. Multiply across thousands of jobs per month and the productivity difference is real. Where the broader question of matching machine class to workload comes back into focus, particularly around segment classification, sits at What the industry copier segments from one through six actually mean for you.

The contrarian case for higher PPM despite the math

One workload pattern flips the FCOT dominance. Offices where multiple users hit the printer simultaneously during peak periods experience queueing delays that PPM solves better than FCOT. If three users send 5 page jobs at the same minute, the second and third users wait for jobs ahead of them in the queue. The waiting time is dominated by PPM, not by FCOT, because the first job is finishing before the next user can start.

For an office of 30 staff sharing one MFP with peak usage clustered around 9 AM and 4 PM, the queueing pattern can dominate user experience. Higher PPM machines clear the queue faster, even if FCOT is slightly slower. The trade off depends on how clustered the workload is in time. Smooth distribution favors lower FCOT. Bursty distribution favors higher PPM.

Most modern offices fall somewhere between the two patterns, with morning and afternoon clusters but reasonable distribution through the rest of the day. The optimal machine balances FCOT and PPM rather than maximizing either one. Where this leads in machine selection is toward middle of the segment options that offer reasonable numbers on both axes rather than extreme values on either. The Kyocera TASKalfa 4054ci with 40 ppm and 4.6 second FCOT exemplifies this balance, and the segment level mapping that puts it in context is at How to tell whether you need an office class copier or a production class one.

FCOT measures the wait the user actually experiences for short jobs. PPM measures sustained throughput on long jobs. Office workloads sit on the FCOT side of the trade off about 80 percent of the time. Reading both numbers, weighting them by the office's actual job profile, and choosing the machine that minimizes total wait per typical job produces better daily user experience than choosing the machine with the highest headline PPM. The faster looking machine is sometimes the slower feeling machine.
