5.3 Cleaning the Printer
As discussed earlier, the following parts must be cleaned
each time the toner container and waste toner box are
replaced:
• Paper transfer unit

In addition to this, it is recommended that these parts are
cleaned periodically at least once a month.

Note
Be careful not to touch the transfer belt (black)

during cleaning. Doing so can cause poor print
