The Printer has an internal clock which allows it to automatically wash the print heads, flushing some ink through the print heads, which keeps the print heads in good condition. The Printer automatically washes the print heads 72 hours after the last printing, and then regularly washes every 3 days. If the Printer has been left turned on and has not been used for 2 weeks or longer, it is necessary to wash the print heads, charge the ink system, and perform daily maintenance using the procedure below. If you have to keep the Printer turned off for a long without using it, first perform a service cleaning using the procedure below, and then turn the Printer off.

Prevent the media from sticking and wrinkling

■ Decrease the platen suction fan level

The vacuum pressure applied to the media in the printing zone helps to hold the media down on the platen, which keeps the distance from media to print heads constant. When the media sticks to the platen, set the vacuum pressure to LOW. The LOW vacuum pressure is also effective when your media is so flexible and easily wrinkled.

■ Change the print head height

The Printer automatically adjusts the print head height to the best position when the Printer is turned on or when a media is loaded on the Printer. However, you may need to adjust the position finely as the media rigidity and temperature response are relevant. To adjust the print head height depending on the loaded media, select MEDIA REG MENU on the operation panel and adjust the print head height.

CAUTION

- Adjust the print head height carefully to avoid the print head touching the media. The print head scratched by media causes the poor ink ejection and degrades the print quality.

On the other hand, a too high print head position also degrades the print quality. You are recommended to operate the Printer with the print head height automatically set by the Printer.

Troubleshoot print quality issues

This section describes the hint for you for one symptom, to get good image quality with the Printer. Take appropriate actions according to the printout's symptom. When several actions are described, they are arranged in the order of effectiveness. Therefore, you are recommended to take actions from the top and confirm the effect on the improvement. (Note that all the described actions are not always necessary to solve the problem.)

The print is light.

Cause Solution

The density setting does not

match.

The operating environment is

outside the specication of the Printer.

Media is not selected properly.

Set density to HIGH DENSITY if high density printing is required, such as when using backlit banner media. (

Raise the ambient temperature to 15°C or more (20 to 25°C recommended) to warm the Printer adequately

Check the media selection. (

Check the obstructions in the nozzle surface path, with the order of on: platen, media edge guards, spittoon case, capping unit, and wiper blade, and remove the obstruction and stains.

Lint or paper fibers caused by a ragged media may touch the print head, which may cause missing dots. Replace the media with a media with no lint or paper fiber.

Check that the exhaust fan filter is not encrusted with dust. If it is, replace the filter.

The media is curled or wrinkled.

Cause Solution

Outside the operating

temperature/humidity range

(1) Use the Printer within the operating temperature/humidity range.

* Note that some media may be wrinkled even within the operating temperature and

humidity range.

(2) Use the proven media.

The media storage conditions

are not the same as the printer operation conditions.

The difference between the media storage conditions and the printer operation conditions may cause the media curled or wrinkled. To prevent it, when carrying the media in storage to the operation area, before printing leave the media for a proper time.

*The time depends on the media type and the storage conditions.

The media was poorly installed. Check that the media was installed properly with the conditions below.

- The installed media is properly parallel to the Printer and the ange.

- The operation panel shows the media type correctly.

- The supply-side tension bar length is proper and it is placed on the center of the media.

- The media winding mode is optimal to the installed media.

The heater temperature wrinkled

the media.

(1) If the media is wrinkled while the Printer is warmed by the heaters, install the

media only after the Printer is warmed up by the heaters.

(2) Change the heater temperature. Increase or decrease the all three heaters by

5°C.

(3) Use the proven media.

The media is curled. (1) Do not use the media curled in the x direction, that is, the vertical direction of

the media.

(2) Do not use the media curled in the y direction, that is, on the right and left

edges of the media. The curl is so excessive that the media edge guards and the suction fan cannot flat the media

(3) Use the proven media.

When the heaters temperature is changed, again adjust the media advance compensation.

Smart pass technology: ON

Smart pass technology

With inkjet printers, a horizontal banding may appear between the bands, which are the areas printed by one scan. This symptom is called as banding. The banding is caused mainly by setting the media advance compensation improperly. With the proper compensation, the bands are linked without gap. However, with the larger compensation the bands are linked with gaps, showing white lines, while with the smaller one the bands overlap, showing black lines. The banding is also caused in the following cases.

- The ink dries so slowly.

- The media advance changes considerably depending on the print head scan.

when the media advance compensation is proper. The overlapping part is processed with the OKI Data Infotech’s unique algorithm so that the bands are not noticeable. The Printer features two overlapping intensities (LOW, MEDIUM). Increasing the process intensity in the overlapping parts makes the banding less noticeable, but decreases the print speed. Increase the overlapping intensity to prioritize quality, and decrease the intensity to prioritize print speed.

With manual print adjustment, the printer prints an adjustment pattern, then the user selects visually an adjustment value and sets the value on the printer.

How to dierentiate between automatic and manual print adjustment

Automatic print adjustment is recommended for the following users.

- Users who do not have much experience with the printer

- Users who find manual print adjustment difficult

- Users who want finish adjustment quickly

* Automatic print adjustment may not be available depending on the media type. If automatic print adjustment does

not improve the print quality, use manual print adjustment.

Manual print adjustment is recommended for the following users.

- Users who needs the best print quality

Cautions regarding automatic print adjustment

NOTE

- The printer cannot set a correct adjustment value through automatic print adjustment in the following cases. In such cases, improve the conditions or perform manual print adjustment.

The automatic print adjustment determines mechanically the adjustment value, so absolute precision of the setting cannot

be guaranteed.

- The media used makes the check via sensors impossible. (Some types of generally used media may also not be compatible with automatic print adjustment.)

- Transparent or colored media

- Media with a rough surface

- Media with an extremely high or low degree of reection

- Media on which the pattern cannot be printed properly, such as when the ink tends to bleed

- Media on which density dierences between adjustment patterns are not visible

- The media surface is soiled with dust, ink, nger marks, etc.

- A gap tends to form between the platen and the media.

- Lots of nozzles are clogged.

- The media heater temperatures are not suitable.

- The environmental luminosity is too strong.

- With automatic print adjustment, the adjustment value is determined through reading of printed patterns. However, the print results of the patterns may vary depending also on the media deterioration due to aging or the media lot.

Therefore, it may not be possible to set a correct adjustment value even when using the same media, leading to a decrease

in actual print quality.

In such cases, use manual print adjustment.

Automatic print adjustment cannot be performed

Automatic adjustment is not possible if one of the following messages appears when automatic print adjustment is performed. In such a case, perform manual adjustment or check the items and perform the measures described below.

MANUALLY ADJUST 1 ADV VAL/PRINT POS

Meaning The amount of light received by the sensors did not reach the

reference level.

Items to be checked Corrective measures

Check that the sensors for automatic print adjustment are not covered with ink mist.

Clean the sensors for automatic print adjustment. (See Clean the surface of the sensors for automatic print adjustment on

page 92

of the Basic Operation Guide.)

Check that the media is clean. Feed the media until you reach a clean section.

Check that the media is not wrinkled.

Check that you are not using a media type with a light reection rate too low.

Reinstall the media or feed the media until you reach a section without wrinkles.

Automatic print adjustment may not be possible with some media types. In such a case, use manual print adjustment.
