BJC-7100 Part 3: Operating Instructions

3) Aligning the print heads

Because two BJ cartridges are installed in the printer, differences in how they are secured and in the cartridges themselves can shift the way ink is ejected onto the paper. To even out any differences and ensure satisfactory print quality, follow the procedure below for adjusting the relative positions of the print heads after completing the setup procedure on the PC.

1)Load two or more sheets of standard A4-size plain paper into the sheet feeder.

2)Following the instructions on the Printer Driver's control sheet, print a Print Head Alignment Pattern.

3)Check the printed patterns to select the optimum A (vertical), B (horizontal), C (bidirectional 1) and D (bidirectional 2) alignment values.

4)Following the instructions on the Printer Driver's control sheet, print a High- Resolution Adjustment Pattern.

5)Check the printed pattern to select the optimum E (horizontal 1), F (bidirectional 1), G (horizontal 2) and H (bidirectional 2) adjustment.

6)Following the instructions on the Printer Driver's control sheet, quit the print head alignment procedure.

7)You can print the nozzle check pattern to check the print head alignment values after completing this procedure. To print the nozzle check pattern, refer to 3.8 Service Mode (Page 3-21).
