Catering printer is a kind of equipment commonly used in catering industry, which can realize the functions of order printing and dish list printing. But sometimes we will encounter the situation that the printer can't run normally, and one of the common problems is that the printer can't be powered on. Let's analyze the reasons.

1. Power cord problem

The power cord is an important part of the normal operation of the printer. If there is a problem with the power cord, the printer will not be powered on. When the power cord is open, short-circuited, etc. , the current will not be transmitted to the printer, resulting in failure to work normally.

2. The power plug is loose

Sometimes we don't notice whether the power plug is fixed or loose due to long-term use, which may also be the reason why the printer can't power on.

3. The voltage is unstable

In the catering industry, there are often a lot of electrical equipment coexisting. At this time, voltage instability is a common problem. If the printer experiences voltage fluctuation or power failure suddenly, the printer may not be powered on.

4. Power switch problem

The power switch is also the key factor that affects the printer's startup. Generally speaking, the printer can only be started when the power switch is placed in the "on" position. If the power switch is faulty or damaged, the printer will not start normally.

5. Circuit board failure

There are many small circuit boards in the printer. If something goes wrong, such as a burned or damaged circuit board, the printer will not be powered on.

In short, the above reasons may affect the printer can not be turned on. When we use the printer at ordinary times, we need to pay attention to the details and use the equipment reasonably to avoid improving possible problems. If the catering printer can't be powered on, first check the above faults and find the corresponding solutions to make the catering printer work normally.
