IQ-17 Toner Image Detection Color Stripes
At Near Empty state, if a customer had removed the Cartridge and knocked on it
to collect the toner towards the exit in attempt to use the very last bit of toner, it
may cause color stripe deterioration.
This can also be caused by a toner cartridge that is exposed to a temperature
exceeding 127º F (53º C) for a short period of time.
Cause
• This error occurs when soft block shaped (clumped) toner is being supplied to
the Developer. The lines are more visible when printing high density images.
Initial Actions
• Check the paper transfer path.
• Ensure there are no debris on the transfer path.
