Checking Your Laser Printer

If your laser suddenly starts making a lot of noise, don ’ t panic. This article provides a simple and practical self-diagnostic guide to help you quickly determine if your equipment is functioning properly.This includes laser equipment noise standards and suggestions for daily maintenance, helping you to solve the problem of equipment noise.

First, determine the environment in which the equipment will be used.

Check to make sure it is level.

The body of the computer can amplify noise, and metal surfaces are especially prone to resonance.Try lightly pushing the machine at its four corners. If it wobbles, put down an anti-skid mat, or adjust its position.

Clean up the surrounding debris.

Paper clips stuck in the paper feed, hair wrapped around the rollers, these and other small things can "choke" the printer.After turning off the computer, use a soft brush to clean the air intake port and air outlet. This is especially important for equipment that is frequently placed on carpets.

The results were compared with those of a control group.

Record the sounds of a healthy body.

When I first got the phone, I recorded a piece of work on it, and later I compared it to see the difference.When a laser is operating normally, it gives off a steady, low-pitched humming sound, similar to the noise emitted by the compressor of an air conditioner.

Changes were observed at intervals.

When the machine is first turned on, it's normal for it to make a high-frequency sound for a brief period. But if it makes a "vroom" sound like a motorcycle accelerating, or a "squeak" sound like metal rubbing together after 20 minutes of continuous operation, then there's a problem.

Three steps to identifying abnormal noise.

Listening for sounds.

He uses a long-handled screwdriver as a stethoscope, gently tapping different parts of the body of the machine, listening with his ear against the handle, and quickly determining the source of the noise.Be careful not to touch the hot parts!

Empty load testing.

Remove all the materials and let the machine run empty. If the noise disappears, the cause may be that the paper feeder is too tight or the medium is rubbing.He recalls one customer who used a damp acrylic sheet, which made a popping sound like fireworks as it was cut.

Decibel test.

Download a noise-testing app to your smartphone and use it to measure the noise level at a distance of one meter from the device.The normal noise level for an office laser printer is 55-65 decibels (about the level of a loud conversation). If the noise reaches 70 decibels (equivalent to a vacuum cleaner), it is recommended that you contact the after-sales service.

Tips for daily maintenance.

Every month, the tracks are cleaned and oiled with cotton swabs, just as with a bicycle chain.I have seen too many cases where fans have been made into "tractors" by accumulated dust.Remember to wait until the system has completely cooled down before disconnecting the power.
