- See the CUPS Canon MG-6100 page on this wiki for pertinent information about setting up the printer under GNU/Linux.
RX-630 (All-in-one printer/scanner/copier)
- At least some Epson ink cartridges and printers contain features that prevent use of the ink inside non-empty cartridges!
- Epson settled one or more lawsuits on this matter.
- After the settlement, cartridges continued to be manufactured with the same "features".
- In the tradition of class action lawsuits, the compensation to the user was insignificant.
- Epson sold affected printers to buyers via their online store after the settlement (without disclosing the issue).
- Without counter-measures, a cartridge can disable the printer even if it is full!
- This needlessly costs the user money.
- This generates unearned income for everyone else.
- Printers routinely report that not yet empty cartridges are empty.
- If the cartridge is removed and shaken or weighed, it is obvious that it still contains ink.
- When affected printers/cartridges report the cartridge is empty, the printer is completely disabled.
- The cartridges have an internally programmed "freshness date". The cartridge is treated as empty if it is "too old" even though the cartridge is completely functional.
- The cartridges have an internal usage counter. The cartridge is treated as empty if the counter reaches some pre-determined value (even though the cartridge is completely functional).
