Hi, I am printing on an i-class printer multiple label formats. We are using a roll of 2.5" continual media and are utilizing the cutting mechanism. One of our labels is printer on the length of the media and is approx 3.5" long this label prints perfect no matter how many copies we request. the issue is with our small label 2" x 1" that we have on a horizontal position across the media. The first label will print and cut immidately following the border, and labels there after will print and then leave enough white space for another label before cutting and printing again. If I form feed between every label it resets and is fine again. Do you have any suggestions as to what might cause this extra white space on additional labels. I thought about the backfeed option before cutting but this only works with single label request, you can't use the qty option. Please help

Re: i-class cutting issues
You need to calibrate the printer using the instructions located in the
manual. This should be in area 5.2 of the manual. If you don't have the
manual you can download them at this address along with software
updates and firmware updates.
Label printers are always finicky. I have strtix printers where I work and they give off wacky errors too.

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

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

2. Make sure that media sensor is positioned correctly.
3. Make sur that media type is set for non continuous labels.

The LP2844 can only print on Direct Thermal labels.
DT labels have the ink within the label and the labels react to heat. If these labels are to be exposed to direct sunlight they will eventually turn black.
If you scrape the label with fingernail you can usually see the black ink on label
The physical size of the labels is this max width 1 inch (MInimum) to 4 inches (Max). Maximum length of label depends on the amount of memory in printer but maximum size for standard LP2844 is 11 inches. With full memory can be 22 inches long.
The labels must be on a 1 inch core.
These printer can handle all label types.
1: die cut Labels - Use gap sensing.*
2: Labels with Black mark on back - Use Black mark*
3: Continuous roll - select continuous *

For the cutter to work it is necessary to instruct the printer to "Use the cutter" This setting is usually accessible in the printer driver. Your label program interacts with the printer driver. Ensure that the cutter option is selected in the printer driver.
The printer must be calibrated or the type of sensor is wrong. Verify that the sensor type is correct for your label (gap or black mark) and you can calibrate it by pressing the FEED key for about 5 seconds approximately.
I am surprised that you are using that sequence of buttons to solve this problem. I am pretty sure that they want you to go into the "Media Sensor Calibration" setup in the config menu. It is a bit more complicated than what you have described. I also believe that the size of the gap on two of your labels might be out of tolerance (they are usually 1/8" gaps between the labels). The black marks are a problem for the transmissive sensors. You may need to move the transmissive media gap sensor (remember it has two parts: upper and lower). I would usually setup mine for a place beyond the black mark so that you are looking at just the white paper.
To start out:
1. Load the backing of a 6" strip of media (no label attached).
2. Remove a ribbon (if you usually use one).
3. Close the printhead.
4. Press SETUP/EXIT and then NEXT/SAVE until "Media and Ribbon Calibrate" appears.
5. Press "+" to start the calibration procedure. You should see the "Load Backing" in the LCD Display. You already have the backing loaded so continue to the next step.
6. Press "+" to answer the message and the next screen should say, "Remove Ribbon". You have also removed the ribbon.
7. Press the "+" to continue. You should see the screen say, "Calibrating Please Wait". After the sensors are setup by the machine a new screen should appear, "Reload All".
8. Open the printhead, and move the labels until they are loaded correctly to print. Smooth out the ribbon and load it correctly.
9. Withe media and ribbon now loaded, press "+" to continue and the machine should say, "Media and Ribbon Calibrate".
10. Press the Setup/Exit button once. It should say, "Save Changes Permanent". Press Next/Save to finish the process.
11. Do a normal calibration of your stock and print a label.
You are done. The machine will run for the labels you have setup the sensors for. Unfortunately, you must do this for each of the media types. To automate this, you could run a Configuration listing, capture the settings you just created for each type of label. Take these to a programmer to have them send the setup to the machine before the job. This is beyond the scope of this type support to really help you.
