My ricoh aficio code a 990 how to fix them ?


An SC990 is usually an error indicating maintenance is overdue. The only way to verify that is by printing out the SMC report and seeing the subcodes. In the case of this model when is the last time the drum and developer was replaced?

This is a known manufacturer error. Call Ricoh Direct and talk to someone in Tech Support. If your product is registered with them, they will send you a new printer. You will have to ship the old one back in the same box the new one was shipped to you in, but they provide an RMA # so there isn't any charge.

Error 990 keeps blinking on machine


This is an error that has to do with the ink drying up on the maintenance unit. This cannot be fixed by the end user and must be fixed by Ricoh. Error 990 is a Ricoh defect in which the printer should qualify for replacement.

Error code 990 indicates software problems yuo can check in SP7-403 for information.
Error code 540 will proberly indicate some heating trouble in the fix, you have to reset the machine with service code SP5-810.
Code 350 will disappear if you restart the copier.

Have error code 990 on ricoh gx 3000 printer how do i clear this?


you can try pulling out and reseating the Waste Ink tank which is located behind the machine behind a plastic door cover (left side of machine as you are looking at it from behind). Turn the machine off and on using the main power switch. If the code comes back then you will more than likely need a new Waste Ink Tank.

ERR (990) or ERR (999) are both error messages which are displayed when a sensor does not work normally due to dirtiness. For example, either may be caused by a dirty maintenance unit or clogged ink nozzles. It may be possible to resolve the issue by cleaning the device
