The things copied by Ricoh copier have bottom ash. How to deal with it urgently, online, etc. Thank you for your help.

None of their answers are correct. It's not about changing powder, it's about changing carrier or drum. I often encounter the problem you mentioned. This is a common problem in Ricoh's low-end copiers, that is, the design defect of the waste powder of the fuselage, especially the copier that recycles waste powder 250 1 200 1 and has no independent waste powder bin. It's because of the waste powder in the delivery bin. The usual solution is to initialize the carrier 1 2 times to make the concentration and strength of the carrier uniform and avoid the problem of bottom ash. The operation mode is to enter the maintenance mode (Huanglou+107), execute code 2 or 5-8 10, wait for a period of time, let the machine fully stir the paper tray, and then start printing 5 sheets again.
