Canon 3788B004BA magenta drum unit toner cartridges (genuine brands)

Genuine Canon magenta drum unit

This genuine Canon magenta drum unit carries model number 3788B004BA and is built for the imageRUNNER ADVANCE C2020, C2030, C2225 and C2230 series. It replaces the imaging drum in those multifunction printers and is supplied new in a single-unit pack. Offices that run those specific Canon models will find the correct fit without adaptation. Buyers who need a toner cartridge rather than a drum, or who operate a different printer family, cannot use this item.

Sustained print performance

The manufacturer rates the drum at an approximate yield of 36000 pages at 5% coverage, with a separate highlight noting 51000 pages per unit. Those figures reflect long-run capacity rather than a short burst, so the drum maintains consistent magenta output across high-volume monthly cycles. Print quality remains stable as the drum approaches its rated life, reducing the frequency of mid-job replacements in busy workgroups.

Installation and common issues

The drum unit slides into the designated magenta slot on the compatible imageRUNNER ADVANCE models and locks with the standard Canon release lever, requiring no tools or firmware steps. Most installation problems arise when the protective seal is not fully removed or when the unit is forced into an incompatible chassis, which can damage the drive gear. Users should verify the exact model series before opening the package to avoid a mismatch.
