Troubleshooting

To perform the cleaning use the Cleaning kit 

(CK832A) included with the printer, see photo.

Use the following procedure to clean fiber/dirt 

from electrical contacts.

1.

Remove the Printhead as described in the 

User’s Guide to gain access to the Car-

riage Printhead Interconnect board.

2.

Once the printhead has been removed 

look down into the empty printhead.s slot. 

Check the status of the electrical contacts 

which are located there. If necessary use 

a light to check the contacts. 

3.

TIP: To clearly see the electrical contacts, 

place a small piece of Z-folded paper 

down into the slot to highlight the contacts 

4.

If the contacts on the printer interconnect 

board are dirty and have fibers on them, 

this will cause the reseat/replace error 

messages. 

5.

Turn off the printer with the ACB1 switch 

and use the brush from the cleaning kit to 

carefully clean the contacts of dirt/fibers. 

Use care when cleaning so that none of 

the contacts are damaged. 

6.

After thoroughly cleaning the printhead 

interconnect contacts with the brush, use 

the Pneumatic air gun to blow any resid-

ual dirt from the contacts and the general 

area.
