Phaser 850 - Screen Dark - Red Light 3 Blinks

[Arketek]

Having a problem with our Phaser 850 in the office this morning. When first powered on (cold boot), the green and red lights light momentarily - then they go out and the red light blinks three times, pauses, and blinks three times again, pauses, etc. Searching gives recommendations based on error codes, but screen remains blank so no error codes.

Many thanks for any insight.

probably a SDRAM problem which is on the mainboard

Seems to be a possible bad DRAM bank in the DIMM.

Found this reference -

- which definitely has a lot of useful information for these printers.

yah thats what that usually ts the board itself.... Try pulling out the Ram and see if you get a different ERROR if you do then you know THAT IT is the Dimm if you get the same error 3 blinks then its gunna be the DRAM Bank 0 closest to the rear panel. Usually that means new printer since the cost of the Mainboard is far greater than the cost of a new printer

Pulled the DIMM in the rear socket and the error disappeared. The user needs the printer, so I'm going to leave it at that for now.

Next is to switch the DIMM from the other socket when I have a chance to see if it is the DIMM or the socket and go from there.
