CP4525 Toner collection unit issue
I have a HP CP4525 printer that is telling me I need to replace the toner collection unit, upon opening the printer and removing the unit, it quite clearly isn't full, I've emptied the unit and cleaned it using a toner cloth, popped the unit back in and closed the printer, however its still saying the unit is full, initially this caused the printer to stop printing, but as a work around to get the printer back in action, I've accessed the AT VERY LOW menu from the manage supplies menu and selected continue.
I'm thinking it could be that a sensor needs locating and cleaning, or that there is a way to reset a page count that affects when the printer tells you that the unit needs replacing, if anyone has any ideas I would greatly appreciate it :)
thanks in advance for any help
