After changing the print head and setting the Ohm resistance, the left side of the printed labels are faded. I adjusted both head pressure and slid them back and forth but I can't get it to print right. Any tips on what I should look for so I know if it requires more/less pressure or if it needs to be moved to the left or right? Thanks

On the right hand side of the print head is a blue thumb wheel. ensure this is set position 9, this will give you full width print. This adjustment is for setting narrow width labels.

I have used this type of printer before. Long ago when it was called the C-ITOH. However, never had to change the print head before. I would imagine that if you did - all the adjustments would need changing. Bad Gap would skip labels and bad pressure would make them too light or too dark. If there are any vertical lines (even faint) the print head is damaged. Also, these things are very specific as to media vs ink roller. You cannot use a paper ink roller with mylar labels. Vise versa works but those rolls are more expensive. I am sure you have tested this already but you point pretty exclusively to the "new" print head with your testing. Sounds like you have answered your own question. I would do some continuity tests on the head to see if it carries any current at all. Good Luck!

If the problem is on the right side , try adjusting the head pressure adjustment knob on the top right side. You can adjust with a flat blade screw driver.

Try cleaning the thermal print head. If that doesn't do the trick, the printhead may be defective.

One of two situations exists:
1. If the printing stops with clear stopping edge, then the PRINT WIDTH setting has been changed from the default full width setting of 104mm.
Check this by pressing MENU and then the NEXT button until you see a setting for MAX WIDTH. It should be set to full width of 104mm. Anything less will stop printing beyond whatever the setting is. Change it back to the full width setting.

2. If the printing stops by fading away to the right side, then that is caused by a pressure imbalance across the printhead. There is more pressure on the left side than the right side. There are two toggles that press down on the printhead and the pressure can be adjusted by moving the right toggle to the right so that more pressure falls on that side of the printhead.

Hope that helps !

Check the label on the back of the printer.
If the configuration has either 10500-2xxx-xxxx or 10500-3xxx-xxxx, you don't have to set the resistance manually, the printer sets it automatically.

Best way to check this is to take your tallest and widest label and print out a configuration label. This is done by turning off the priner, pressing the CANCEL key and holding while turning on the printer. Release the button when the calibrate led turns off. A config label will print and you can check the setting for PRINT WIDTH.

2. If the printing stops by fading away to the right side, then that is caused by a pressure imbalance across the printhead. There is more pressure on the left side than the right side. There are two toggles the press down on the printhead and the pressure can be adjusted on each by turning the knob on top. Readjust the right side until printing returns across the label.

Hope that helps !

Not too sure what you mean here. If the print on the left side is Ok and faded on the right side, then the position of the printhead pressure toggle may need to be adjusted. Make sure it is positioned over the center of your label.

Hope that helps !

I think the 105 has an adjustment on the printhead. There are left and right hand adjusters just above the printhead. It sounds as if the right hand one does not have enough pressure on it, try increasing the RH one and see the effect on the print.

Check the printhead pressure. there is an adjustment screw that does this. It could also be that your platen roller is worn or that your printhead has burned out pixels.
