Unacceptable Print Quality; The Printer Does Not Print Or Prints Several Labels At Once; The Ribbon Does Not Advance - Datamax E-Class E-4304 Operator's Manual

Unacceptable print quality:

Dirty printhead. Clean the printhead, (see Chapter 5).
The printhead temperature is too high. Use the software
control to adjust the Heat Setting, Print Speed, or adjust the
darkness adjustment located on the back of the printer.
The incorrect ribbon/paper combination is being used, check
the ribbon type being used.
Faulty Printhead, replace, (see Chapter 5) or call for service.

The Printer does not print or prints several labels at once:

The labels are incorrectly loaded, see the loading
instructions on the inside cover of the printer, or Chapter 3.
The media is not calibrated, (see Chapter 4)
The media sensor or media sensor circuitry may be
defective, call for service.

The ribbon does not advance

(The printer advances paper but ribbon does not advance).
The ribbon is installed incorrectly. Open the printhead and
make sure that the ink side faces the paper. With most
ribbon this can be verified by rubbing paper against the
ribbon, the ink should smudge the paper. With label stock
use the sticky side of a label, the ink will stick to the label.
A bad ribbon/paper combination is resulting in an
insufficient amount of friction between paper and ribbon.
Ensure that the correct type of ribbon is being used.
