80 PX4ie and PX6ie High Performance Printer User Guide
Clean the Media Guides
The label stop sensor is covered by two plastic guides. The guides are transparent
to allow light to pass between the two parts of the label stop sensor. These areas
must be kept clean from dust, stuck labels, and adhesive residue.
If your printer starts to feed labels in an unexpected way, pull out the upper guide
and check for objects such as dust, adhesive residue, or labels blocking the beam
of light. If necessary, clean the guides.
To clean the media guides
1. Open the front door and media cover.
2. Pull the upper guide straight out and press the snap-lock, lift the edge of the
lower guide, and pull the lower guide straight out.
3. Clean the guides with a cleaning card or soft cloth moistened with isopropyl
alcohol. Be careful not to scratch the guides.
4. Replace the upper and lower guides.
Warning: Isopropyl alcohol [(CH3)2CHOH; CAS 67-63-0] is a highly
flammable, moderately toxic, and mildly irritating substance.
