4 • Troubleshooting/Diagnostics
Possible Cause/Solution
1. Remove cartridge and tap it upside down
on a desk two times.
2. Remove print head. Check that tape has
been removed from the ink port on the
bottom of the ink cartridge.
3. Replace printhead and make sure it is
properly seated. When it snaps into place,
push it up against connectors.
4. Install ink cartridge and run test print.
5. If print is still poor, weigh the ink cartridge.
If 1.5 oz. or less, the cartridge is empty.
If between 1.6 to 1.9 oz., perform two "B"
purges and run a print test. If 1.9 oz. or
more, perform two "B" purges and run a
test print. If necessary, perform up to five
"C" purges, making test prints between
each one. If this fails to correct problem,
printhead is suspect.
1. Contact PbP to see if the correct ZIP Code
can be flagged.
2. If PbP is unable to flag the ZIP Code, trans-
fer the customer to Change of Post Office.
3. The CPO agent will make the correction
and flag the ZIP Code for change at PbP.
4. Instruct customer to perform a PbP bal-
ance inquiry. The correct ZIP Code will be
downloaded once the mailing system has
made a successful connection to view bal-
ances.
1. Reinstall print head and ink cartridge.
Check for bent pins when you do this.
Make sure cap was taken off printhead
and tape removed from cartridge. Check
that print head is snapped into position.
2. Reboot.
3. Check PH ribbon cable and connection at
J127.
If, after trying all of the above there is still no
detection, replace print head.
