Frequently Asked Questions
We just put in fresh toner, so why are copies still coming out streaked and grey?
Because toner is only half the print. The GPR-22 toner cartridge supplies the powder; the drum unit — this part, Canon part number 0388B003AA — is the surface that carries the image onto the page. When a drum wears, the signs are different from an empty cartridge: the same mark or line repeating down page after page, a grey background haze that never fully clears, and defects that stay in exactly the same place no matter how new the toner is. If a fresh cartridge changed nothing, the drum is where to look.
Is this drum the same purchase as a GPR-22 toner cartridge?
No — they are two separate consumables that work as a pair. The GPR-22 toner cartridge (0386B003AA) is the one you replace every 8,400 pages or so. This GPR-22 drum unit (0388B003AA) is rated for up to 26,900 pages, so it typically outlives roughly three toner cartridges before it needs changing. Ordering one when you meant the other is the most common mistake with this platform, which is why the part numbers matter: 0386 is toner, 0388 is drum.
How long should a 26,900-page drum actually last us?
It depends on your monthly volume. At around 1,000 pages a month, a 26,900-page rating stretches to roughly two years. At 2,000 pages a month it is a little over a year, and a hard-worked department machine at 3,000 pages a month will get through it in about nine months. The rating assumes standard 5% page coverage; heavy, dark originals and dense copies wear the drum surface faster than plain text does.
$122.56 is a lot for one part — what does it work out to per page?
Spread over its rated life, $122.56 across 26,900 pages is about 0.46 cents per page — under half a cent. We will be straight about the comparison inside this family: this is the expensive drum of the GPR range we sell, because it is a precision imaging component, not a powder refill. But priced per page rather than per box, it is one of the smaller lines in the machine's running cost, and it is far cheaper than retiring a working copier over print quality.
Which copiers does this drum unit fit?
This GPR-22 drum unit (0388B003AA) is built for Canon's imageRUNNER 1023, 1023IF, 1023N, 1025, 1025IF and 1025N multifunction copiers. If your machine is one of those six and it takes the GPR-22 toner cartridge, this is its matching drum. Machines outside the 1023/1025 family use different drum units, even where the toner names sound similar.
What happens if we fit the new drum and the prints are still not right?
First, it is covered: this drum carries our 1-year warranty against defects and 1-year free returns if it does not perform as it should, with full terms on our shipping and returns page. Second, an honest note — if a new toner and a new drum both fail to clear a defect, the cause is likely elsewhere in the machine, and a service visit is the sensible next step rather than a third consumable. Our support team is available Monday to Friday, 9 AM to 5 PM CST and can help you work through which it is.
