Frequently Asked Questions
What should the first pages look like after I fit this C9800 set?
Clean and even: solid blacks, smooth color fills and no streaks or patchy bands. It is worth printing a couple of test pages with all four colors on them straight after fitting — if anything looks off at that point, it is far easier to sort out immediately than after a long print run.
Does the Premium Quality listing cost more than the standard C9800 set?
No. Both are $292.17, and both carry the same up-to-15,000-page rating on each of the four cartridges. The Premium Quality words sit in this listing's title; the price and the specification stay exactly where the standard listing puts them.
What arrives in the delivery?
Four sealed compatible cartridges — black, cyan, magenta and yellow — from the 42918901, 42918902, 42918903 and 42918904 family. Fit them all for a complete refresh, or hold colors back and install them individually as the old ones finish.
Which machines take this family?
The Oki C9600hdn, C9600hn and C9600n, plus the C9800hdn. The number printed on your outgoing cartridge — one of 42918901, 42918902, 42918903 or 42918904 — is the check that settles it.
If output still looks tired with new toner, what then?
Then toner was probably not the culprit. Persistent fading or background shading with fresh cartridges fitted usually points to a drum or another wear component reaching its limit — worth knowing before you blame, or replace, a second set of toner.
What warranty and returns apply?
One-year warranty and one-year free returns across the set, detailed on our shipping & returns page. Orders ship from whichever of our Illinois, Pennsylvania, Georgia or California warehouses is closest to you, and support runs Monday to Friday, 9 AM to 5 PM Central.
