Media Properties
Store media flat, in a clean environment with the same or similar temperature and humidity as the
printer.
For best results, individual sheets of media should be flat. Curves in either axis of the media (left to
right, or front to back) can lead to head strikes of the carriage on the media. Accuracy of dot
placement or overall feed accuracy can also be affected by non-flat media.
For best results, media should have parallel opposite edges with 90° corners. Media that is not
square with itself will require extra attention when loading.
The maximum weight of the material per printer specification is less than 125lbs. (56.7 kg).
For materials between 50-250 lbs. (22-113 kg), choose Heavy when selecting weight in the Media
Wizard when to set the media belt drive motor and media advance interval.
The front and back of the material should be clean and dry.
Some substrates may have different feed and handling characteristics from sheet to sheet.
Some substrates may have a coating on them; giving the effect of a glossy image. Certain coatings
may cause ink to pool and cure unevenly, yielding a poor image quality print. Be sure to test
coated materials for compatibility before purchasing significant quantities.
Be careful to avoid substrates with bent or damaged edges on the material, especially engineered
material such as Alumacorr or Dibond. They may create drag along surfaces such as the belt and
cause a significant change in feed or cause the material to skew.
Heavy substrates or sheets with a significant bow or bend will feed differently on the belt than
when contacting the output table rollers. Adjust the belt vacuum fans to Maximum to determine if
the media will suction to the belt; removing the bow. If unsuccessful and the job or size of the print
job allows for adjustment, use a leading margin of four to six inches.
Other Printer Configuration Notes
Certain print modes and lamps settings can have an effect on handling characteristics such as
feed and skew because the material may bow. Increasing the head height and increasing the print
speed may balance this. Introducing a print pause or increasing the belt vacuum control may be
necessary.
Perform media feed calibrations in a representative manner relative to the way the substrate is fed
through the printer.
