Step 5
You can now remove the two pins that
hold the cartridge together. These are
tapered pins pushed in from the outside,
so they must be removed from the inside
of the cartridge. With the drum shutter
held back, use a long punch or bent
extraction tool, and tap, then press, the
tapered pins out from the inside on both
ends of the cartridge.
(See Photo 5 and 6)
The OEM pins can be reused during
re-assembly, or after-market pins which
have a shoulder (allowing them to be
removed from the outside) can be used
instead. Set the toner hopper aside for
now.
