Antztech,
if the red light is coming on and staying on, it might be a sensor problem. Try pushing on the lid and see if the light goes to green. If it does, it' s the gap sensor. This is how the printer "reads" the labels gaps-the little spaces between the labels. We've solve this in the short term by covering the sensor and manually setting the gap through the programming command prompt,

Check media settings in the printer driver. Check version of printer driver. Zebra printersuse an internal printer driver with their Zebra Designer software (Zdesigner driver) or a ZUD (Zebra Universal Driver) for other windows applications. These drivers can be downloaded directly from the zebra website.

Alternatively you can download the seagull scientific driver and use that instead. (used with bartender program)

Label skipping occurs if the media dimensions are not specified correctly. The important ones are label height, and media setting for type of media.

Perform a media calibration before you go changing settings. Power on printer, Hold top and bottom buttons in on control panel for 5 seconds, release bottom button only then when printer starts feeding labels release top button. When printer finishes press feed button.

Check the drive belt. It might be missing a tooth if the printer is older. I can assist if you want to check this.

If you are using a ribbon remove it and perform a calibration, hold down feed key for 2 seconds as you power on, release key and wait for it to complete its calibration, when it has stopped shifting labels (wait for 10 secs to be sure) HIT THE FEED KEY to exit dump mode. If it has successfully calibrated it will feed a label each time you hit feed key. Re-install ribbon, make sure ribbon is pushed formly onto drive sprockets and then re-run the calibration..

If this does not fix problem. download firmware to latest version. This will automatically reset printer to factory default condition.
