Samsung SF-555P Toner Cartridges

(Continued)

Figure 30

26) Replace the fuse on the top of the cartridge with a new 63mA fuse. The fuse should be taped in place to it
does not fall off. See Figure 30

Running a cleaning page

The SF-555P has the ability to run it’s own cleaning page. This page according to Samsung will clean any toner
particles off the drum that may be stuck there.

Press the SETUP key on the front panel.

Press the Right or Left ARROWS until “MAINTENANCE” appears.

Press the START/ENTER key.

The display will show “CLEAN DRUM”

Press the START/ENTER key.

A Cleaning page will then print.

Cleaning the Scanner

These machines can also be adjusted for a dirty scanner. Personally I would just clean it, but there may be a time
where this procedure becomes useful (When the scanner starts to fail) so I am including it here.

Load a sheet of CLEAN bright white paper into the scanner

Press the SETUP key on the front panel.

Press the Right or Left ARROWS until “MAINTENANCE” appears.

Press the START/ENTER key.

Press the Right or Left ARROWS until “ADJUST SHADING” appears.

Press the START/ENTER key.
