How can I solve E14 code on Gestetner copy printer 5308

SC code:E-21 Paper exit timing sensor remains off
E-22 2nd feed timing sensor remains off
E-23 Master eject position sensor remains
E-24 Feed start timing sensor remains off

point to check- Feed start timing sensor

dirty sensor or failed, air line to get dust off my first step.

Clean paper exit feeders

Bad thermal head. Very expensive.....

Paper table is not moving. Check wire harness.
