The Zebra LP 2844 is a direct thermal label printer that was designed specifically for offices that need high-quality label printing but do not have a lot of room for a large printer. To produce barcode labels that can be accurately read by barcode readers, the printer must be calibrated and aligned. The Zebra LP 2844 needs to be calibrated and have its thermal print heads aligned on a consistent basis. When your Zebra does not calibrate, there are troubleshooting steps that should be attempted prior to sending the printer in for service.
AutoSense Calibration Method
Turn the printer off. Let the printer sit idle for at least one minute.
Use the proper recommended paper to feed into the printer. Make sure that the paper is clean and is not damp or that was stored in a humid area. Many calibration issues are caused by humid, old or dirty paper.
Press and hold down the "Feed" button. You must hold this button down before proceeding to the next step.
Turn on the Zebra printer.
Release the "Feed" button when the printer lights begin flashing. Once you release the feed button, the printer lights will flash green a few times and will advance the paper into the printer.
Press the "Feed" button after the printer prints out a listing of the internal information. Pressing the feed button after this information is printed will bring more paper into the printer and will correctly calibrate the paper and print heads. Once completed, your Zebra printer should be aligned, calibrated and ready for use
