• Full weight = 1880 grams (66.3 oz)

 

• Empty weight = 1450 grams (51.1 oz)

 

Note: Some toner might reside in the waste toner cavity, which affect the

 

weight of the cartridge.

 

2. Perform the half self-test function check (see page 224) or try a toner

 

cartridge that you know is full and functional. Replace the toner cartridge if

 

necessary.

No transfer-roller voltage.

Without transfer-roller voltage, toner does not transfer correctly from the

 

surface of the drum to the paper. Perform the half self-test functional check

 

to check all other electrophotographic processes (see page 224). Replace

 

the transfer roller if necessary.

High-voltage connector springs are dirty or defective.

The high-voltage connectors are mounted on and above the dc controller and protrude into the toner cartridge cavity.

Check the springs for functionality. Clean if dirty, replace if defective or missing.

No drum ground path.

With no ground path, the drum cannot discharge. The negative charge on

 

the drum repels toner, and leaves a nearly-white page (possibly with bubble

 

print).

 

Check the drum ground that runs from the contact point in the center of the
