1. To unclog print head nozzles, perform print head cleaning or deep cleaning through the printer maintenance window. This will clean the nozzles. 2. Print a nozzle check pattern to check the cleaning results. Look for missing lines or streaks, which indicate clogged nozzles. 3. If cleaning does not work, nozzles may be defective, requiring ink cartridge replacement. Cleaning consumes ink, so do it only when needed.

How to prevent smudge or paper abrasion
To adjust the gap between the print head and the paper, set the paper thickness lever properly according to the media being used.
When the paper other than an envelope/T-Shirt Transfers is scratched, setting the paper thickness lever to the right position may
improve this problem.
( The images below show the iP2200 model. )
Note:
When paper other than an envelope/T-Shirt Transfers is abraded, setting the paper thickness lever to the right position may
improve this problem.
However, continuous printing in this setting will likely smear the inside of the printer.
Therefore, return the paper thickness lever to the left position after printing.
- Paper other than envelopes/T-Shirt Transfers -> Left side

4. - Envelopes/T-Shirt Transfers -> Right side

How to curl paper
When using 4" x 6" or 5" x 7" sized paper, to prevent paper abrasion, curl the paper in advance.

5. 1. Put a sheet of paper not used for printing on the paper's print side < 1 >.
2. Without touching the paper's print side, roll the paper and hold it in place for approximately 10 seconds.
Note:
If you touch the paper's print side, print quality may deteriorate.
3. Remove the paper not used for printing and confirm that the paper's print side < 1 > is curled within 2 to 5 mm (0.2 in).
Memo:
Set the curled paper sheet by sheet in the printer.

How to unclog print head nozzles (Windows)
If print results are faint or streaks are printed, the print head nozzles may be clogged.
Those phenomena can be improved by performing print head cleaning (Cleaning) or print head deep cleaning (Deep Cleaning).
Also, you can check the cleaning results by printing the Nozzle Check Pattern after the cleaning of the print head nozzles.
<Procedures>
To check and improve the condition in which the print head nozzles are clogged, follow the instructions below.

8. (Memo)
If missing lines still appear on the Nozzle Check Pattern printing even after Deep Cleaning, ink cartridges may be defective.
Cleaning, Deep Cleaning, and Nozzle Check are performed through the Maintenance window.
Do the following to open Maintenance.
1. First, open the Properties window.
- For Windows XP Home Edition
Click/Select "Start," "Control Panel," "Printers and Other Hardware," and "Printers and Faxes."
- For Windows XP Professional Edition
Click "Start" and "Printers and Faxes."
- For Windows 2000/Me/98
Click/Select "Start," and "Settings," then "Printers."
2. Select the Maintenance tab.

9. *Display varies according to the printer model.
<How to print the Nozzle Check Pattern>
1. In the Maintenance window, click Nozzle Check.
2. When the Nozzle Check window is displayed, move the paper thickness lever to the left, and load a sheet of A4 or letter size
paper in the auto sheet feeder.
Then, click Print Check Pattern, and printing will start.
(Memo)
When clicking Initial Check Items, the confirming items before performing the nozzle check pattern printing will be displayed.
3. When the confirming message is displayed, click OK.

10. Do not perform any other operations until printing is completed.
4. Check the printed nozzle check pattern.
*Display varies according to the printer model.
(Memo)

printed.
The BK pattern will not be displayed in the window either.
[When the output is normal]
Black ink: The grid pattern is regular without missing lines.
Color ink: White streaks are not visible in the pattern.
[When the output is not normal]
If the following cases can be seen, perform the cleaning of the print head nozzles.

<Case D>
There are white streaks in one of the color ink patterns.
<How to perform Cleaning>
1. In the Maintenance window, click Cleaning.
2. The cleaning of the print head nozzles starts.
3. When the confirming message is displayed, check the contents, and click OK.
Although the Nozzle Check window is displayed, do not perform any other operations until Cleaning is completed.

12. (Memo)
- During Cleaning, the Power lamp blinks green.
- Cleaning consumes a certain amount of ink. Note that if performing Cleaning often, ink will be consumed quickly.
4. When Cleaning is completed, the Power lamp will stay green.

<How to perform Deep Cleaning>
1. In the Maintenance window, click Deep Cleaning.
2. When the Deep Cleaning window is displayed, check the contents, and click Execute.
(Note)
Cleaning consumes a certain amount of ink. Note that if performing Cleaning often, ink will be consumed quickly. Furthermore,
