Hi

Sorry if this has been asked before but here goes.

Recently on my HP laser a faint vertical line has appeared on print outs
towards the right hand side of the page. It is a line of slightly darker
output than the area around it.

Is this a simple cleaning task and if so what do I clean or is it the end of
the drum or one of the cartridges.

My tool box page shows that the drum is 84% and the toners are B=86% C=1%
M=1% Y=57%

Any assistance would be greatfully received.

Derek
