Ink Delivery System (ID)
For issues with missing or non-recognized ink cartridges, a standard good practice is
to remove all ink cartridges, then insert them one at a time and run the "qa" command.
In this way, the actual cartridge can be identified, instead of the confusion that may result
with bus contention or an incorrectly chipped cartridge. If two identically chipped
cartridges are inserted (for example, chips indicate two magentas), one will show as
authentic, but the incorrectly chipped cartridge will show up as missing.
ID01: Ink Cartridge Not Recognized When Inserted
The message "ink tank missing" appears on the screen. Querying the QA status may
reveal that the cartridge is not authenticated or missing.
Cause
Tanks may not be making contact with the pads that read the chip. This happens if
the tank is noti inserted fully, the pads on the printer are damaged, or the chip is not
located properly on the tank. Chips can also be faulty and fail to read even when the
contact is good.
Solution
Shim bottom of tank to make contact.
1. If the tank is now seen as present, then the contacts on the printer PCA may be
damaged.
2. If the tank is still reading as missing, then the chip on the ink cartridge is
nonoperational. It is possible for a chip on the tank to be working normally and then
not work properly. Try replacing with a different ink cartridge.
ID02: Ink Reported As Out When Not Out (Excess Stranded Ink)
The printer reports empty ink and refuses to print, but the cartridge still has more
than 7CCs remaining.
Cause
The primary cause of excess stranded ink is false early detection from the ink low
sensor, See "Ink Low When Not Low" for details. There are firmware settings to adjust the
allowable ink that can be used after detection. This is currently set to zero as of
10/21/2010. On average, an additional 2CC can be used, but the distribution is not well
controlled, and using a nonzero number will not completely protect the user from
running out of ink while printing.
This could damage the head, so it is avoided at the expense of excess stranded ink.
Solution
1. See Low Ink When Not Low. CMs have two avenues to adjust what happens between
ink low detection and ink out protection. First, the nvm flag can be set to false so that the
printer will only warn about ink out but will not error and prevent printing. Second, the
allowable ink after low ink detection can be set to a nonzero number, which will enable
most users to print a few more CCs of ink but expose some users to the risk of dry-firing
the head.
