The printer was lock how to open the printer - Epson POS TMT88IV Thermal Receipt Printer

Canon Pixma MP270 error E05

Your printer does have a lock that clicks in when you open the printer to replace ink catridges. The User Manual has no specific comment on steps required to release the lock.

Is there a release tab/button that you grip when lifting? If so, suggest you try pressing this same release as you lift the cover, lifting slightly higher to see if the lock will disengage allowing you to close.

If no release tab/button simply try lifting slightly higher as above to see if the lock will disengage.

If either of these does not resolve isse I would inspect losely to see if there is a way to disengage the lock; simply using more force may result in damage.

Friend if the printer states that the printer cover is open. it means that the cover of the printer is open or not locked. the cover above the cartridge is the one mentioned.
1. Be sure to lock or closed the printer cover before printing because if it is open it will not print because the software automatically detect the unclosed part of the printer.
2. check whether the hinges is safely attached it can be found in the printer cover side attached to the body of the printer.
3. try to see if there are some pieces of papers attached or stuck in the cover that's why it detects uncover.
4. clean the cover with soft cloth remove the dust and other dirt.
