Frequently Asked Questions
At $372.67, how does this set justify itself on a production cost sheet?
By the pages behind the price. The four cartridges average $93.17 each, and for that the set puts a 36,000-page black (2790B003AA) and three 27,000-page colors (2794B003AA cyan, 2798B003AA magenta, 2802B003AA yellow) into an imageRUNNER ADVANCE C5030–C5240 class machine. On a production floor the comparison is never cartridge against cartridge — it is the cost of a planned set against the cost of a stopped machine and a rush order, and on that comparison a stocked set wins most months.
On a C5235 running reports with color covers, which slot empties first?
Follow the ratings and the workload together. The colors are rated 27,000 pages against the black's 36,000, and cover-and-chart work spends color on page after page while the black mostly prints body text. In that mix the color slots usually call first. A mono-heavy workload flips it — the black does the lifting and its larger rating is what keeps it in step. Meter readings, not the calendar, settle it for your machine.
Should the full set go in during a planned maintenance window, or one cartridge at a time?
One at a time, as each slot asks — but use the maintenance window to check the shelf. There is no gain in retiring a cartridge with life left in it, and the set's cartridges are independent units. What a service visit is good for is confirming the spare set is complete, so the next change, whenever it lands, is minutes of work instead of a stoppage.
We run a C5035 and a C5240 side by side. Can one shelf set serve both?
Yes — that is one of this family's practical strengths. The same GPR-31 set fits the imageRUNNER C5030 and C5035 and the ADVANCE C5030, C5035, C5235, C5235A and C5240, so a single spare set on the shelf covers every machine in that row. Fit cartridges wherever a slot calls, and reorder a set when the shelf box is opened.
How should a set at this price be stored and rotated?
Sealed, flat, cool and dry, out of direct sunlight — and dated. At $372.67 the set is a real asset sitting in the supply room, and the only discipline it asks is first-in, first-out: when a new set arrives, it goes behind the existing stock, not in front of it. Nothing in the box needs opening before its slot calls for it.
What backing comes with the four cartridges?
The same backing as every compatible cartridge we sell: a 1-year warranty and 1-year free returns, cartridge by cartridge, with the full terms on our shipping and returns page. Support is available Monday to Friday, 9 AM to 5 PM CST, and sets ship from our Illinois, Pennsylvania, Georgia or California warehouses.
