How to fix ghosting on photocopies in three steps

Ghosting is the appearance of a faint image from a previous print on the current page, usually positioned somewhere below the intended print. The effect comes from the imaging cycle's memory of the previous page, which the device fails to fully reset between cycles. The cause sits in one of three subsystems: the fuser holding heat from the previous image, the drum retaining residual charge, or the cleaning blade missing toner from the previous rotation. The three step procedure below resolves the issue in over 80 percent of cases without service intervention.

Recognising ghosting versus other artefacts

Ghosting always shows a faint version of an image that appeared earlier in the same job. Bands and streaks repeat regardless of content. If the faint mark on the page resembles text or graphics from a previous page, the issue is ghosting. If it shows a repeating pattern unrelated to content, the issue is banding or wear, covered separately in the cluster.

Ghosting that repeats at a regular interval down the page traces to a rotating component: usually the drum, occasionally the fuser. Ghosting that appears only once on the page, in a single fainter copy of the original image, points to the fuser or to charge retention rather than to rotation.

The three step resolution procedure

Step One

Print 10 blank pages to reset the imaging cycle

The simplest first step is to print 10 consecutive blank pages through the device. The blank pages give the drum, the cleaning blade, and the fuser ten complete cycles with no image content, which lets each component shed any residual toner or charge from the previous job.

Why this works. Most mild ghosting cases trace to incomplete cleaning of the drum between pages on a heavy coverage job. Ten blank pages let the cleaning blade catch up with the toner residue and restore the surface to a neutral state.

Print the test page that originally showed the ghosting after the ten blank pages have completed. Inspect the result. If the ghosting has cleared or reduced significantly, the issue was residual buildup that has now resolved.

Use plain paper from a fresh ream for the blank pages
Print at full size A4, not eco mode or reduced format
Wait 30 seconds after the ten pages complete before printing the test page
Compare the test page against the original ghosting sample side by side

Step Two

Run the device's image quality calibration cycle

If the blank pages did not resolve the ghosting, the next step is the device's built in image quality calibration. The calibration runs an automatic sequence that resets the imaging registration, adjusts the laser intensity to match the current drum and developer state, and clears the imaging memory of any retained content. Most devices include the calibration under the maintenance or service menu on the front panel.

Why this works. The calibration cycle takes the device through every imaging step in sequence, including the steps that clear charge memory and reset the fuser thermal profile. A successful calibration brings each subsystem back to its reference state and resolves ghosting caused by drift rather than wear.

Allow the calibration to complete fully without interruption. Most cycles take three to seven minutes. After the calibration completes, print the test page again and inspect for ghosting. A calibration that resolves the issue means the underlying components are healthy and the fault was in drift accumulation across a long job sequence.

Locate the calibration cycle under Settings, Maintenance, or Adjustment depending on the device
Confirm the device is at operating temperature before starting
Wait for the cycle to complete and the device to return to ready state
Print a fresh test page from a different source than the original job

Step Three

Inspect and clean the drum unit and cleaning blade area

If both prior steps fail to resolve the ghosting, the issue has moved beyond drift and into a physical condition that needs attention. The third step is to remove the drum unit for the affected colour and inspect the cleaning blade area for accumulated toner residue or blade damage. The cleaning blade rides along the drum surface and removes residual toner after each transfer cycle. A worn or damaged blade fails to clean cleanly, leaving toner traces that produce the ghost.

Why this works. A cleaning blade that has accumulated dried toner along its edge no longer makes uniform contact with the drum. The non contact zones leave toner residue that picks up image content from the previous cycle and prints it as a ghost on the next page. Cleaning the blade often resolves the issue; replacement is needed when cleaning does not work.

Remove the drum unit following the front panel instructions. Locate the cleaning blade, which sits along the back side of the drum housing. Wipe the blade edge with a clean microfibre cloth lightly dampened in 70 percent isopropyl alcohol, in a single direction matching the blade length. Reinstall the drum unit, reset any counters if prompted, and print a fresh test page.

Work over a clean surface to catch any loose toner that falls during inspection
Avoid touching the drum surface directly; hold only the housing
Inspect the cleaning blade edge for visible chips or wear
Replace the drum unit if the blade shows damage rather than residue

The three types of ghosting and what they signal

Cold ghost

Appears on the first few pages of a job, fades by page five or six. Caused by fuser thermal recovery between cold start and operating temperature.

Resolves on its own after warm up

Drum memory ghost

Appears at a fixed interval down the page, matching the drum circumference. Caused by drum surface retention of charge from previous content.

Step 1 or step 2 usually resolves

Blade ghost

Appears as a faint image of the previous page somewhere lower on the current page. Caused by cleaning blade missing toner residue.

Step 3 usually resolves

Fuser ghost

Appears further down the page than blade ghost, often with a slight gloss difference. Caused by fuser sleeve retaining thermal image of previous content.

Fuser replacement usually required

Preventive measures that reduce ghosting frequency

Three habits reduce the frequency of ghosting on a healthy device. The first is breaking long heavy coverage jobs into smaller batches with brief pauses between them, which lets the cleaning blade catch up rather than falling behind across thousands of consecutive pages. The second is running a calibration cycle once a week, which keeps the imaging system reset and prevents drift accumulation before it shows on prints.

The third is using paper within the device's recommended weight range. Heavier paper absorbs more heat from the fuser, which leaves less thermal margin for the next page and increases the chance of fuser ghosting. Sticking to the recommended weight, typically 75 to 90 gsm for office prints, keeps the fuser operating within its design envelope and reduces thermal ghosting cases.

When the three steps do not resolve the issue

If all three steps complete without resolving the ghosting, the most likely cause is a worn or damaged cleaning blade that cleaning alone cannot recover, a fuser sleeve approaching end of life, or a transfer issue that requires service diagnosis. The next step is to log a service call with a clear report of which steps were taken, what the ghost pattern looked like, and which type from the four above matches most closely.

The service engineer typically inspects the cleaning blade for damage, the fuser for sleeve wear, and the drum for surface degradation. Replacement of one of these components usually resolves the persistent ghosting, and the maintenance counter is often near the threshold where the replacement would have been scheduled anyway.
