8-2. Major Functions
(1) Borderless printing (4"x6", 5"x7" size only)
The iP1000 supports borderless printing only for 4"x6" and 5"x7" size paper. Borderless printing is not
supported with other paper sizes (A4, LTR, etc.).
< Possible problems with this function >
- Smearing on the address side of postcards in continuous borderless printing on the message side.
-> Clean the ribs on the platen.
- Smearing on the backside of paper in continuous borderless printing.
-> Clean the ribs on the platen.
- Ink mist on the platen.
-> Clean the ribs on the platen
(2) No paper selection lever
The printer does not need adjustment via a paper selection lever. (Adjustment of the head-to-paper distance
when printing envelopes is not necessary.)
< Possible problems with this function >
- The head rubs against the paper when the amount of paper curl is large.
-> Flatten curled paper (to less than 3 mm).
-> In print modes other than borderless printing, conduct printing in the print quality assurance
area of the top and bottom edges. (Top margin 28 mm, bottom margin 26.5 mm)

(3) Quiet mode

The printer has a quiet mode function.
Compared with the normal mode,
Acoustic noise level:
Audible overtone level:
Print speed:
(4) Remaining ink level detection function
The printer has a function to detect the remaining ink level. (Default setting: ON)
Detection method: Dot counting (Counted for each BK/CL ink tank)
Display method:
Accuracy:
Slightly lower. (HQ, normal: Approx. 48 dB, Quiet: Approx. 47 dB)
Sound quality changes, and sound becomes quieter.
Slows. (BK printing in HQ/HS mode using an acoustic noise measurement
pattern: Approx.1.3 times)
CL tank: The remaining ink level is detected by total counted dot values of 3
colors of ink.
Displayed on the Status Monitor (at 3 levels listed below for each BK/CL ink tank)
Level 1:
Half level of remaining ink level (Approx. 40% of ink remaining)
Level 2:
Indication of "!" mark (Approx. 10% of ink remaining)
Lever 3: Indication of "?" mark (Remaining ink level is unknown, ink may be used up
anytime)
Note:
Remaining ink detection function displays the status only, and does not cause
errors.
The margin of error of detection accuracy is +/-10% in normal printing.
The margin of error is likely to be large in the following specific print patterns:
When printing continuously using any one of the CMY colors of ink
-> As the remaining ink level is calculated by total counted dot values of 3
colors of ink, if any of the C/M/Y inks is heavily consumed, the margin of
error for remaining ink increases.
When performing continuous BK solid printing
-> With continuous printing, ink flow from the tank to the ink chamber can be
interrupted, after which ink remains unused in the tank.
