Replacing The Printhead - Intermec EasyCoder PX4i User Manual

Replacing the Printhead

EasyCoder PX4i Bar Code Label Printer User's Guide (IPL Version)
The printhead is subject to wear both from the direct thermal
media or transfer ribbon and from the rapid heating and cooling
process during printing. Thus, the printhead will require periodic
replacement.
Time between printhead replacements depends on the print
images, the type of direct thermal media or ribbon in use, the
amount of energy to the printhead, the print speed, the ambient
temperature, and several other factors.
While replacing the printhead, the power must be off. The
firmware will not detect the new printhead resistance and
density until the printer has been restarted.
Note: Check that the density of the new printhead matches the
printhead you are replacing. While you can switch between
densities at will, the printout will be affected accordingly.
Note: Prior to installing the 406 dpi printhead on the PX4i
printer the firmware must be updated to IPL Firmware version
2.74.0 or higher.
To replace the printhead
