The Konica Minolta bizhub catalogue has two generations sitting side by side on Spanish dealer listings: the older C-series (2015 launch) and the current i-series (2019 launch, refreshed for 2026). Both run on the same Simitri toner family; both share the bizhub brand on the front panel. Beneath that surface they differ on eight structural points that change the day-to-day experience for users and the management surface for IT. This guide walks each difference in turn, with an upgrade-decision matrix at the end for offices on a lease renewal window.
Stable, capable office workhorses across the 2015 to 2018 chassis generation. Still in service on Spanish floors on lease cycles signed 2019 to 2022.
The current chassis, with a unified UI shared across the AccurioPress production line. Carries every feature the 2026 refresh added, including AI scan classification.
The EU Cyber Resilience Act takes effect in late 2026. The C-series cannot meet the firmware-signing requirement; the i-series ships compliant out of the box.
The 12 percent energy reduction on Simitri V toner pays back roughly 80 EUR per device per year on a 12K-page monthly load. Multi-device fleets see four-figure annual savings.
The dual-pass DADF doubles the throughput on the scan workflow that drives most office document handling today. Document-heavy offices see noticeable user-facing improvements.
| Cost line | Stay on C-series · 5 years | Upgrade to i-series · 5 years | Delta |
|---|---|---|---|
| Hardware | 0 EUR (already owned) | 5,200 EUR (or lease equivalent) | +5,200 EUR i |
| Energy use over 5 years | 680 EUR | 600 EUR | −80 EUR i |
| Drum and consumables | 3,600 EUR | 3,400 EUR | −200 EUR i |
| Service contract | 2,400 EUR | 2,400 EUR | 0 EUR |
| Productivity gain from faster scan | 0 EUR | −1,800 EUR (estimated, mid-size office) | −1,800 EUR i |
| Security incident exposure | Higher · uncovered by Cyber Resilience Act | Covered | Risk reduction |
| 5-year total cash cost | 6,680 EUR | 9,800 EUR | +3,120 EUR upgrade premium |
The arithmetic above puts the upgrade premium at around 3,100 EUR per device over five years, with the security and productivity benefits sitting against that figure. Offices that quantify the scan productivity benefit at more than 1,800 EUR per device close the gap. Offices in regulated sectors (healthcare, legal, financial services) see the Cyber Resilience Act exposure as the deciding factor, since the C-series cannot meet the signing requirement.
From the eight differences listed above, two stand out as the most-cited reasons for upgrade decisions in the Spanish dealer network. The first is the dual-pass DADF, which doubles scan throughput at no incremental operator effort. The second is the embedded security stack, which is a hard requirement under the Cyber Resilience Act and a soft requirement under most public sector tenders. Offices that are scan-heavy or regulation-heavy land on the i-series for one or both of these reasons. Offices that are print-only and unregulated see less compelling reasons to upgrade before lease end.
Spanish dealers pitch the i-series upgrade in three steps. First, an audit of the C-series device against the Cyber Resilience Act compliance checklist; offices in scope see this audit as the conversation starter. Second, a one-week scan throughput trial with an i-series demo unit alongside the existing C-series; the throughput delta usually shows up in the trial logs. Third, a lease quote that includes the i-series unit, the Workplace Hub stack if the office wants it, and the migration of HyPAS-equivalent apps to the new chassis. Most upgrades complete inside two weeks once the lease paperwork is signed.
For Spanish buyers placing the upgrade decision into context, the bizhub brand and 2026 lineup overview sets the wider strategic backdrop. For buyers heading into production-class workloads, the AccurioPress production series guide covers the production-tier siblings of the i-series. For ongoing fleet owners, the J1 and J2 jam code decoder covers the day-to-day operator surface that both generations share.
