011. Laser printer powder box structure
The structure of the laser printer powder cartridges consists mainly of sensor drums, carbon powder storage, waste powder collection, scraping boards and various panels。
The working method is that laser beams launched by lasers are trans-reflected by a mirror into the acoustic deflector, while the two-indicated graphics-point information sent by the computer is delivered through the interface to the font generator to form the required font-shaped binary pulse information. The signal from the syncor controls the high frequency oscillator, and the refrequency synthesiser and power amplifier are added to the acoustic modulator to adjust the laser beam。
The rationale for laser printers
2. 1 optical and visible processes
The laser beams are transducered by acoustic modulator, and are shot into a multi-faceted mirror, which is then focused through a wide-angle focus lens and then to the surface of the light-guided selenium drum. The surface of the accelerator is recharged by charging poles, followed by the exposure of laser beams into an electrostatic image, followed by a magnetic imager, which transforms the inhaled image into visible ink. In the trans-print area, ink powder is trans-printed to plain paper, where text and images are then condensed through high-temperature thermal rollers。
2. 2 clean system functionality
During the printing process, the cleaning system removes unreprinted ink and residual charge on drums to ensure that the next round of printing is carried out smoothly。
Common problems and solutions
3. 1 printers are not responsive
If the printer does not respond, the following steps can be followed: first, checking whether the printer's power supply and print line are connected properly; second, observing the light status on the printer's panel and identifying the problem on the basis of tips; then finding the printer in the computer's “control panel” “printer and fax” to ensure that it is on-line; and lastly, trying to re-install the driver。
3. 2 printing of causes of and responses to disorder
In addition, problems with the printing of random laser printers may be caused by a number of causes, such as long or damaged computer connections, printer-driven program failure, failure of the main board or document damage. The problem could be solved by looking at each of these possible causes。
3. 3 reasons for leakage problems
In the case of leaking powder, it may be caused by the ageing of the powder box, poor sealing or improper use. The condition of the powder box needs to be checked and appropriate measures taken to address it。
According to maintenance experience, the reasons for the uncoded laser printer printing may include: excessive computer connection lines (over 3 metres) or damage; printer-driven program failure (re-installation required); printer master plate failure (remaintained by professional engineers); and document damage (re-opening or preservation required). Users can identify and resolve problems by looking at these possible causes one by one。
