Frequently Asked Questions

The M603XH fades mid-shift with a queue behind it — what is the drill?

Pause nothing you do not have to. Let the current job finish if its pages are still acceptable, then swap at the next natural gap: top cover up, old CE390A out, spare in, cover down. The queue holds throughout. Total interruption is about two minutes, and the waiting jobs print in order afterwards.

Who on a shift should do the swap?

Whoever finds it — that is the point of this machine's setup. The swap needs no tools, no login and no technician: rock the new 90A, pull its tape, seat it until it clicks. If your workplace designates one person, make sure the spare's location is written on the machine itself for the day that person is absent.

Why rehearse the swap before it is needed?

Because the first attempt should not happen against a deadline. A two-minute practice run on a quiet afternoon — open, out, in, test page — means the real mid-shift swap is muscle memory. Machines of this class earn their keep on uptime; the cartridge change is the one planned interruption, so plan it properly.

Does the high-capacity tray setup complicate the change?

No. The XH configuration's extra paper capacity lives below; the cartridge bay is on top and independent of it. Paper stays loaded, trays stay shut. The only interaction is positive: fresh toner plus full trays is exactly the state a long unattended run wants to start from.

What does a fresh cartridge restore, in numbers?

A full 10,000 pages at standard coverage from a $48.70 CE390A (90A) — the complete rated life, not a top-up. On a machine that measures work in thousands of pages per shift, that is the difference between scheduling around toner and forgetting about it for weeks.

What if the mid-shift swap does not fix the fading?

Reseat the cartridge once, firmly. If output stays faded with a fresh unit correctly seated, stop and call us — support runs Monday through Friday, 9 AM to 5 PM CST, and every cartridge carries a 1-year warranty and 1-year free returns. The shipping & returns page covers delivery and returns.
