Hello, I am using a three part continuous form. I have followed the user manual and have the TOF and ATO set perfectly. Now I need to find how to adjust the width of print. I have the Tractors set as far as possible to the right but the print is still approaching 1/2" further to the right than where it needs to be.

The Media Sensor is not seeing the labels or is not configured for these labels. Check Media Sensor position and settings. The Fixed Sensor models have a small window for the sensor at the bottom of the printer, about 3/8" to the right of the left side. If the printer has a movable sensor, the typical position is either 1" to the right of the left edge of the labels, or in the center of the labels. Typical media sensor setting is "Gap Mode". Another common issue is that the sensor might have a piece of label or something stuck to it, covering the lens. Finally, there is a possibility that the reflectivity threshold may need to be recalibrated (see below). This can be difficult, although there are instructions in the Operator's Manual. If physical position/clear view of labels by sensor doesn't seem to be the issue, an easier way to deal with settings issues might be to Restore to Factory Defaults (see below).
Datamax E-Class Auto Media Calibration Procedure:
The 'Auto Media Calibration Procedure' allows the operator to
automatically obtain the optimum (TOF Low and TOF Delta) values for
a particular media. These values are useful for media that continues to
have troubles after Media Sensor has been manually calibrated (usually
preprinted media). This operation feeds 10 inches of media using the
current Media Sensor Calibration setting and calculates the TOF Delta
and TOF Low values to be used. Upon completion the printer will exit
back to 'Calibration Mode' flashing the PAUSED light if successful or
the FAULT light if not successful.
Note: Before calibrating, be sure the media sensor is set for the
appropriate media type, see section 4.4.2, also be sure the
printhead is latched down and the cover is closed.
To perform the Auto Media Calibration complete the following steps:
1. Load the desired media.
2. Hold the button while powering up the printer. Continue to hold
the button until the PAUSED light turns off then release.
3. Next press the button, (the printer will now calibrate to the
4. The PAUSED light will flash 5 times to indicate a successful
calibration. The FAULT light will flash 3 times to indicate an
Note: If you wish to discard your changes and revert back to the
previous calibration simply turn off the printer before Step 5.
5. Now you can save your changes and resume by again
pressing the + buttons simultaneously.
Datamax E-Class Reset to Factory Defaults Procedure:
With the printer off, press and hold the F1, F2, and F3 buttons while
turning the printer on. Continue to hold the buttons down until the
PAUSED light turns off. The printer will now be set to the 'Factory
when the paper loads, the top of form is then set., If the printer is not setting this or the paper just feeds through when loading paper, go into the test menu, select pcalib and make sure no paper is in the printer. aslo make sure the printer is not in direct sunlight. this will reset your paper detection circut and therefore your tof "alignment"
If you are using regular letter size continuous printer paper, load the paper normally with the machine turned off. You can even turn the knob to feed the paper through, it doesn't matter how far. Turn the printer back on and press "PARK" button. Then press the "FF/LOAD" button and when you begin printing it will automatically print at the top of form (TOF). If the TOF ever gets thrown off you can press "LINE FEED" until the tear is where you want it and press "SHIFT" > "TOF" to back back to the previous page (or top of form). Simply put, pressing "PARK" then "LOAD" should set the tear where you need it.
Most likely problems: Wrong sensor set in the media type area. Gap, Reflective. If the incorrect meday sensor is set, the unit will give a TOF error. If you hae pressed the feed button and kept pressed for at least 4 labels, and it does not automatically calibrate, check the type of sensor. If you still get error, and the correct sensor is set, do a complete calibration.

The requires to be programed to attain the new accessories installed. Usually the printer would continue functionality once depleted supplies have been replaced. However, power off the entire computer and peripherals, disconnect every link allow to rest for some moments, reconnect the entire setup. Once powered on the new setup should be recognised. For example, the computer would display a message asking to allign the new printers settings. Attemptign to print a sheet should display further instructions of lists that are choices to allign for appropaite appearance of documents and ink impressions suitable. Once chosen an appropiate allignment display for the new setup, that becomes the deafult until suppplies reequire reinstallation.
There are two things to consider here: 1) Is the printer set to the correct media handling setting? Look in the manual for the terms BAR-SENSE and GAP-SENSE and make sure that you have sent the correct command to the printer. 2) There is a TOF or Top of Form setting that you can send to the printer to align the perforation of the labels with the tear bar. Look for the syntax in the manual, which is free for download at zebra.com, and make sure that your perfs line up with your tear bar.
If I understand correctly, this TOF action involves moving the paper backwards until the top edge moves past the paper (paper out?) sensor. Perhaps this sensor, either an optical sensor, or mechanical switch is covered up by an extraneous piece of paper, or, if mechanical, stuck or broken.
Also the sensor itself might be bad, and not sending the logic circuit a valid signal. This could be checked with a voltmeter or oscilloscope especially if you have an accurate idea of what voltages should be.
