Printer seems slow

You may experience a temporary delay while the printer's drying and curing modules are warming up.

In some circumstances, the printer will deliberately print more slowly than usual to prevent the printheads from

overheating. There are several possible reasons why a printhead may start to overheat:

●

The room temperature is too high.

●

The printhead is suﬀering from blocked nozzles (see

Check and clean the printheads

on page

●

The printhead is faulty and should be replaced.

Request to reinitialize the carriage

In some cases you may be asked to reinitialize the carriage. This operation restarts some mechanical

subsystems, avoiding the need to restart the whole printer.

Internal Print Server cannot detect the printer

If the Internal Print Server cannot establish communication with the printer, without apparent reason or after

modifying Windows properties, follow these steps.

Use the

Wake up

button in the

Power

menu to try to reactivate the printer.

Turn oﬀ the printer’s main switch, then turn it on again after 10 seconds and restart the built-in computer.

Check the cable connecting the built-in computer to the printer.

Check that the Internal Print Server is correctly set up.

Contact your service representative.

Color calibration fails

Automatic color calibration may fail occasionally.

You may see the alert

Color calibration canceled because of scanning errors

, which can be caused by various

diﬀerent problems.

●

Reﬂective color measurements of the printed target cannot be performed reliably on the current substrate.

Reﬂective color measurement can be unreliable or impossible on substrates that are non-white, transparent

or translucent, very glossy, or have a very rough or punched surface. For these substrates, automated color

calibration using the embedded spectrophotometer may not be possible.

●

Some of the color measurements of the color calibration test chart are defective due to:

–

Stains or printhead crash marks on the substrate, that can be easily seen by visual inspection of

the printed chart. Make sure the substrate has no stains before running color calibration. Printhead

crash marks may occur when the substrate is wrinkled. See

There are wrinkles and ink smears on the

substrate

on page

266

–

Wrinkles or bubbles in the substrate, even when there has been no printhead crash.

–

Generally poor print quality (such as banding). See
