How do I solve 1537 errors on my Epson x890, x900 printer?

It happens one or many cartridges aren’t able to maintain air pressure.

Medium to severe air leak combined with older printer firmware will cause a 1537 error.

Despite some customers managed to temporally fix the heat-seal joint between the cartridge membrane and the case; Epson recommend it replacement. Last inserted cartridge is usually corresponding to the faulty one. For additional information please refer to Epson x900 Field Guide: Page 218.

Note: Upgrading to latest firmware revision reduced potential occurrence of this issue.  See “firmware upgrade” topic covered above.
