Bent ink cartridge connector
You may find that the ink cartridge connectors have become bent while the cartridge was disconnected (see
Remove an ink cartridge on page 72). This means that they cannot connect properly, and you will see a reseat
message.
To correct this problem, use pliers to straighten the connectors so that they will fit into their slots.
Printheads
Cannot insert a printhead
1. Check that you are inserting the printhead into the correct slot.
2. Use the correct procedure to change printheads, through the Internal Print Server. See
Remove a
printhead on page 75 and Insert a printhead on page 78, bearing in mind the special tips for the
optimizer printhead.
3. Check that there is no obstruction in the printhead slot.
4. Check that the printhead is correctly oriented (compare with the others).
The Internal Print Server recommends replacing or reseating a printhead
General recommendations
1. Remove the printhead.
2. Reinsert the printhead into the carriage and check the Internal Print Server message.
3. If the problem persists, exchange the printhead with the printhead of the same color in the other row.
4. If the problem persists, check the printhead contacts for dirt or aerosol and clean them if necessary. See
Clean the printhead contacts on page 209.
5. Find more troubleshooting information in the following sections,
Problem due to overheating
on page 250 and Problem due to the primer system on page 250.
6. If the problem persists, insert a new printhead.
7. If no printhead works in that slot, call your service representative (see
HP Customer Care Centers
on page 259).
Problem due to overheating
A printhead may overheat for several reasons:
●
The room temperature may be too high.
●
The printhead may be suffering from blocked nozzles. You may be able to cure this problem by cleaning
the printheads (see
Check and clean the printheads on page 81).
●
The printhead may be faulty, in which case it should be replaced.
Problem due to the primer system
Primers are important to the printheads’ nozzle health. When there is a problem with a primer, the Internal
Print Server displays the following messages.
