5.2.15 A3+ Photo Quality Ink Jet Paper 2 Print Pattern
Printing Function
This function is designed to check whether all adjustment results are normal or not.
For this pattern printing, use Photo quality ink jet paper.
This function prints the following patterns. The check point in each pattern is as
follows.
!
Protection counter
The counter that indicates the amount of ink discharged to the Waste ink pads is
printed in decimal. The counter can count up to 60352, but if the count is more
than 42200, contact and notify the user that the Waste ink pads should be replaced
soon, and recommend the user to change the Pads.
!
Solid print patterns
This pattern is to print to stabilize the printing before printing the check patter and
adjusted patern. This pattern is not printed to check the printing quality. Therefore,
there is no necessity to check this pattern.
This pattern is composed with VSD1 360 dpi x 360 dpi mode and is not enough to
fill out the each dot space on the Photo Quality Ink Jet Paper.
So, the uneven printing or white line will be appeared on the Photo Quality Ink Jet
Paper. Especially, if the Platen Gap is set to + position, the uneven printing
occurred certainly.
!
Dot check patterns
In these patterns, check the dots for thin or thick dots, density inconsistency,
vertical alignment, satellite, and missing dots. Print each color in three different
dot patterns in order of VSD 1, VSD 2 and VSD 4 of BK from top left to right.
If any pattern is found abnormal, perform Head cleaning. If the problem still
persists, change the Head.
!
Head angle check patterns
Make sure that each light magenta line are located at the center of black lines.
ADJUSTMENT
!
Bi-D adjustment patterns
Make sure that there are no displacements between the vertical rules of each VSD.
!
PG parallelism check patterns
Make sure that the CR main shaft and sub shaft are parallel with each other.
(Whether the left and right of the shafts are parallel can also be checked.) Make
sure that there are no gap and overlap between the print pattern blocks.
(Gap and overlap specifications: Within 0.18mm)
!
Head ID
The Head ID value saved in the EEPROM is printed.
!
USB ID
The USB ID value saved in the EEPROM is printed.
!
PF measurement value
The mechanical load in the PF motor ring line is printed.
If the value is as indicated below, check for lubrication, foreign matter, etc. since
the mechanical load is large in the PF ring line. Replace the PF motor as required.
"
When the Cutter is not fitted, the PF measurement value in the ES 3 mode is
near to 79 (if it is 79, Fatal error occurs).
!
Destination
The destination set in the adjustment program is printed.
!
Remaining ink amount
The remaining ink amount of each Ink cartridge currently loaded is printed in
percentage. (100% is displayed if the cartridge is not yet used.)
