What to do if the cash drwer can not work well after using a period of time
Electromagnets are generally 12V printers with 12V cash drawers and 24V printers with 24V cash drawers.
As long as the voltage is matched, it may not be bad even if the cash drawer is scrapped.
Most of the reasons for this problem are caused by customers with 24V printers. If the frequency of use is too high, the solenoid coil may be damaged. In part, it is because the environment of usage is not so good that dust enters the interior of the coil of the solenoid valve. It will also result in the cash drawer can not be ejected smoothly or accidentally.
The cash drawer is the transmission components, the same as machine . It also requires proper maintenance. To deal with this type of problem is very simple, as long as the solenoid inserted into the core and clean up the interior on it. If conditions permit, it may be better to add a little bit of sewing machine oil to lubricate.
