FEED ROLLER ADJUSTMENT

Feed roller adjustment is used for fine tuning label tracking. By adjusting the pressure between the upper and lower rollers, the media may be directed through the printer as desired. If mal- adjusted, the label media will have a tendency to want to track to the left or to right depending on which side has the greatest pressure.

A properly adjusted upper and lower feed roller assembly will have evenly applied pressure to each side and be properly aligned. The pressure difference between each side should be 100 grams or less. A tension gauge will be required to measure the tension.

To acquire the desired adjustment; the upper, the lower, or both feed rollers may require manipulation. Each roller may be adjusted along opposing X and Y axis. Different variations may be required until the correct adjustment is achieved.

1Switch the printer off and disconnect the power supply cord.

2Open the top and right side housing covers.

NOTE: Figures 10-1, 10-2, and 10-3 of the Diagrams & Schematics section provides guidance on housing cover, media, and ribbon removal.

3Remove label stock from the printer and leave print head open.

4Attach a strip of 20mm + wide liner backing paper to the end of the tension gauge.
