Calibration (Gap Sense and Bar Sense)

    By default the printers are set up for bar sensing (black mark) If you are NOT using bar sensing, one needs to tell the printer what type of media it has.

    The gap sensor must be clear to be able to detect gaps between labels

    The sensitivity of the gap sensor can be adjusted using the GAP-SENSE command

Calibration (ZPL enabled printers)

    If using ZPL emulation, the printer needs to be calibrated before it will recognize label lengths within ZPL.

Page width setting (CPCL)

    Mobile printers assume that the page width is the full width of the printer.

    **There is an option on some of the newer printers for a optional media width auto-sensing feature.

Tear off adjustment

    The PRESENT-AT command can be used to position the media at the tear bar of the printer or at a location where the printed label can be easily removed by the operator.

Take label sensor inoperable

    With the printer set for peel and present mode, the label feeds and the printer may not detect the label correctly if the label present sensor is blocked.

    With the printer set for peel and present mode, the label feeds and the printer may not detect the label is present if the printer was not calibrated correctly.

Media does not feed

    Be sure the printhead is closed and latched.

    Check the spindle holding media for any binding.

    If the unit is equipped with label present sensor, insure the last label printed is removed. Also insure the label sensor is not blocked.

Skips labels (Form feed)

    The hexadecimal value "0C" is used by the printer to designate a form feed action. Hexadecimal "0C" is an unprintable character. If received the printer will advance the paper to either the next index mark, or the length specified by the PAGE-HEIGHT, SETFF or SET-TOF commands. (The index mark is either a black line on the back of the stock, or the gap between labels)

"EZ Peel" Peel off mode

If you plan to use the printer in the peel-off mode, peel a few labels off of the meda and pull it out the printer. Close the media cover. Rotate the "EZ-Peel" peeler bar until it locks into place. Then rotate thelatch assembly to the closed position as shown in the links to these photographs:

Not detecting black mark

    By default the printer uses mark sensing (black mark on the back of the labels)

    If the mark sensor is blocked the printer may not be able to detect the black mark.

    The black mark needs to travel over the mark sensor in order for the printer to be able to detect the black mark.

    The sensitivity of the black mark sensor can be adjusted using the BAR-SENSE CPCL command.
