Flashing red LED.

Flashing red LED.

Xpress M 2835 DW printer.

Printer works OK.The LED flashes all the time.

When I press the Blue on/off button (and it goes off) the status screen shows:- "Prepare new imaging unit" with the red LED still flashing.When the Blue on/off button is on the status screen shows "Sleeping" and the red LED is flashing.

Toner status is OK at all times.The only slight problem is when printing envelopes, it sometimes takes a few tries to get it right.....

This is just because your printer's imaging unit is about to expire and its warning before expiry.


if you want to disable this Install Easy printer manager (As your printer is non display printer) and go to settings then disable imaging unit low alert .. pls check below image for more clarity.
