Phaser EX7890

Dependable, everyday office printing is the Xerox Phaser EX7890's whole brief — the no-drama reliability offices expect from the Phaser name. Toner is ordered by number: 106R00654 for magenta, 106R00652 for black, 106R00655 for yellow and 106R00653 for cyan, four cartridges that between them cover everything the machine prints. Its drum unit, 108R00581, follows its own replacement schedule and asks for attention only when the pages themselves start to complain.

A reliable printer disappears into the office routine, and its supplies should too. The pattern with this model is set-and-watch: levels decline slowly and unevenly, black first, colors as the work demands, and the machine speaks up in good time before anything actually runs dry. Owners who keep one eye on that rhythm rarely think about toner at all — which is rather the point of buying a machine like this in the first place.

Drum unit, sold separately from the toner above: 108R00581 drum unit cartridge, black. The drum is an imaging part with its own service life, so it is replaced on its own schedule rather than with every toner change.

Which cartridge should you buy?

Order the way the machine empties: by the single color, as it is called for. The 106R00652 will be your most frequent purchase; 106R00653, 106R00654 and 106R00655 follow at their own pace, and each swap takes minutes. The model 4 Color Set has its moment when the whole row is low — often after a big color job — and the same four cartridges appear as the 4 Color Set and the Premium 4 Color Set for anyone who prefers those listings. The only order that should never be routine is the drum: it is separate, long-lived, and bought on evidence of failing print quality, not on a schedule. Check the rating printed on each product page when you plan a stock-up.

Chip, toner and everyday use

When a cartridge nears its end, the printer warns before it stops, and that warning window is the time to act: order the named color, and keep printing meanwhile. If pages begin to fade before the replacement lands, lift the cartridge out and rock it slowly from side to side a few times — the remaining toner redistributes and usually carries you through. Avoid the two classic mistakes: shaking a cartridge hard over the machine, which invites spills, and pulling a color that still has life in it just because its neighbour ran out.

Frequently Asked Questions

Only one color has run out. Do I have to replace all four?

No. Every cartridge in this printer is its own unit with its own level. Replace the color the machine names and leave the others to finish their lives — that independence is built into the design.

How long will a cartridge last in this printer?

It depends on what you print: ratings are set at five percent page coverage, so reports and letters stretch a cartridge while dense graphics shorten it. The rating for each cartridge is stated on its product page — use it to compare listings, not as a date on the calendar.

Which toner cartridges does the Xerox Phaser EX7890 take?

Four numbered cartridges: 106R00652 black, 106R00653 cyan, 106R00654 magenta and 106R00655 yellow. The imaging side is the separate 108R00581 drum unit, which is a different part from toner and is replaced far less frequently.

My prints look streaky even with a fresh cartridge. What else should I check?

The drum. Streaks that survive a cartridge change usually come from the 108R00581 drum unit, which lays the image onto the page before toner is applied. When new toner changes nothing, the drum is where the fault lives.
