The laser printer should not make any loud or strange sounds during the inclusion, warm-up, and printing. The user may hear a squeak that notifies about the readiness of the printing machine to work or the sound of capturing the page – this is considered the norm. If the printer makes a crackle and strange sounds during operation, then immediately call the master.
Why the printer cracks, knocks and makes noise
- incorrect assembly/installation of the cartridge;
- clogging of the gearbox;
- wear of the gear block;
- during assembly, the gears were incorrectly installed;
- wiped elastic band on the knot of the paper grip;
- the thermal film was torn.
The printer cracks, whistles and clicks – what to do?
Remember how long ago the printer was prevented? Have you tried to refill the laser cartridge yourself or repair the printer? Perhaps the cause of the breakdown was non-compliance with the rules of operation. Do not forget about the natural wear of parts.
Check the cartridge
After refilling, the cartridge knocks if you incorrectly set the gap between the drum and the dosing blade. This situation is dangerous because the drum for any mechanical damage (chipping, scratch, scuff) must be replaced. The printer makes a lot of noise when printing, even when the dust is clogged in the gears of the cartridge or the rubber bushings of the rollers wear out – in this case, you will hear an unpleasant whistle. We recommend that you refill the cartridge in the workshop or call the master at home.
If you did not relegate the cartridge, then try to reinstall it. Open the lid, remove the cartridge and insert it into its original position. There were also situations when users bought fake or incompatible cartridges. In this case, the consumable becomes in the grooves incorrectly, and the printer buzzes or knocks when printing.
Attention! To not be mistaken with the choice of consumables or not to become a victim of counterfeiting, we recommend that you purchase cartridges in large online stores or services. You can buy cartridges for laser printers in the service center. We offer affordable prices and a quality guarantee until the end of the resource.
Clean the gearbox
The gearbox consists of many moving parts – gear mechanisms. When the prevention of the printer is rare, then dust from toner and paper accumulates inside the device. Dirt gets on the metal shafts and is mixed with lubricant. As a result, the laser printer will fasten and whistle when printing. Paper clips, coins, and other garbage could also cause extraneous noise. In this case, it will be enough to disassemble the printer, remove all dirt and apply fresh lubricant.
Check all moving parts of the printer for wear and tear
The laser printer has plastic gears that can wear out over time. Gear teeth are erased or break when the device is overloaded. In this case, the printer is noisy and does not print. Finding interchangeable components for new and outdated models can sometimes be difficult, so seeking help from a large specialized printer maintenance service is better.
Verify that the printer is assembled correctly
Many users are trying to eliminate the cause of a particular malfunction independently. Disassembling the printer is one thing. But then, there may be problems with the reverse assembly of the device. When the parts are installed incorrectly, the printer cracks when turned on and printed, and at the output, the sheets turn white. Try to rebuild the printing equipment case or seek help from specialists.
Note! If you need prompt and high-quality repair of the printer, you can contact our service center. At the end of the work, the master will issue a warranty card confirming the quality of the service. We strongly recommend not to try to repair the printing equipment yourself – this can lead to other breakdowns and take a lot of time.
Inspect the paper gripper unit
The printer’s paper capture unit (solenoid) is triggered when a piece of paper needs to be grabbed. This part is equipped with a rubber gasket. Over time, the rubber band can lose weight, and then the metal lever hits the metal plate of the solenoid magnet. The laser printer knocks when printing and can grab pages every once in a while or chew paper. It is enough to remove the old piece of rubber band and seal the place with insulating tape to get rid of the knock.
Take a look at the thermal film
When the printer cracks when printing, it may be in the thermal film. Paper clips, buttons, and other foreign objects could get into the printing compartment. They become the reason that the thermal film is torn, and there are extraneous sounds during the operation of the printing device. How do I resume my printer or MFP? It is necessary to replace the thermal film.
Laser printer clicks and knocks – useful information
Is it possible to avoid such breakdowns? Yes. Just listen to the recommendations of the masters:
- perform a preventive inspection and cleaning of the printer in a timely manner;
- do not try to repair the equipment on your own;
- relucking and buying cartridges from trusted workshops
- check drafts before use for paper clips and buttons.
If your printer is knocking, cracking, buzzing when turned on or printing, it is better to immediately call the service center and call the master for diagnostics. By solving the problem early, you can protect the printer from more serious breakdowns and yourself from additional costs.
