Replacing the Print Head
The print head on the TDP4*H printers is a user-replaceable item. If it becomes damaged for any reason, it can
be easily removed and replaced. Contact the
PANDUIT
ID Division for information on obtaining a new print head.
The TDP4*H is available with three different print heads with 203, 305 or 609 dpi (denoted by replacing * with a
2, 3 or 6 in fourth digit of part number). Make sure you have the correct replacement head as the printer will
automatically detect the print head resolution and load the operating parameters for that head.
