tional assistance, please contact our

Coating:

If the coating metering controls are set and the finished product appears in need of more coating or

has no coating at all, you will need to increase the Form Roller to Impression Roller pressure.

If the coating is better on one side (left or right) than the other, you will need to adjust the Form

Roller to Impression Roller parallel adjustment. (See the Setting the Form to Impression Roller

Pressure section in this Operators Manual)

3. If you have decreased the Form Roller to Impression Roller pressure and are still getting too much

coating on the job, you will need to adjust the coating metering controls on the Coating

Unit.

4. The coating metering controls will generally be run between 2 to 3. There is an adjustment on the

left and right side for fine-tuning the amount of coating. Remember MORE IS NOT BETTER.

5. A larger number on the dial will give you a smaller amount of coating on the job.

If the coating scratches off frequently when tested with your finger nail, it may indicate that your UV

Bulb needs to be replaced. Contact

UniNet

Customer Service.

7. After running several test sheets, if the printed area looks good but the unprinted area looks like it

requires more coating, you paper may be absorbent. This can be fixed by decreasing the coating

unit pressure and/or changing to a higher viscosity coating.

Testing for Absorbent Paper, Toner & Ink

With the

iColor coater

Belt ON (UV OFF) run and coat one (1) sheet through the

iColor coater

and

remove it.

2. Set this paper aside for 2 or 3 minutes and then inspect it. If it appears that almost no change has

occurred to the coating, then your print media and paper are not the absorbent type.

3. If either the print media or the paper appears to be losing the coating, then one or the other is

absorbent. This is not a coater problem but a paper or print media problem.
