Manual Jet Mapping Each of the printheads used by the printer has 512 ink jet nozzles (jets). If any one of these jets is clogged or has a bad electrical connection, print quality may be affected. A certain number of non-firing jets is within the performance specifications of most printers that use this technology.

Using a patent-pending technique, the printer “fills in” the pixels that were not printed by the non-firing jets, without reducing print speed. The end result is that every print is made with no missing pixels.

The printer automatically maps out missing jets that are not firing for electrical reasons. Jets that are missing or misfiring for other reasons are usually detected during the AutoSet or AutoJet calibrations. You may also map jets manually using the following procedure.

Tip

AutoSet incorporates an automatic version of this

 

calibration. Try AutoSet first before running this

 

manual calibration (see “AutoSet” on page 4-2for

 

details).

 

 

 

 

Tip

For best results, before performing this procedure,

 

clean the printhead jets as described in “Cleaning

 

Ink Jets” on page 5-3.Autodetected missing jets

 

sometimes can be recovered by carefully wiping the

 

electrical contacts on the printhead and their corre-

 

sponding contacts on the printhead carriage with a

 

lint-free wipe moistened with plain water.
