hi piz Error code P9 and P21 appears on screen and when printing or photocopying using color black, blank copies are outputed
SOURCE: code error p9 p21 p16 c203 what can i do?
The p error codes you have are due to the test pattern being put on to the transfer belt to check the image density control
The first thig to do is to check and see the condition of the transfer belt and if it has reached life or looks bad replace it also on taking out the transfer belt directly where it goes in there is a cover slide the cover and clean out the idc sensors imgae density control sensors
Also there is firmware to correct the issue do this last the above will get rid of your issuesAlso add toner to all the units manually add the toner as well
