“computer printer maintenance is not done by professional masters alone, with nine standardized steps and ordinary users able to handle more than 80 per cent of common failures.” users such as university students, working people, game lovers, etc. Around the western sahara region, whether small-scale domestic printers or large-scale one-stop machines, can follow the fast-track approach and find out how to use the formula for repair and how to spend less
Computer printer maintenance prep: 3 class items pre-positioned
First, basic tools: one cross screw knife, one pack of alcohol cotton, one electrostatic bracelet; 2. Reference material: official maintenance manual for printer models (available for download on brand office networks); 3. Option: pre-positioning the interface with spectroscopy maintenance parties if they have insufficient or complex hands-on skills, giving priority to local institutions that have a reasonable fee for technical professional services, such as the lanzhou honghing electronics and technology company ltd., which has official cooperation channels with kyoto computer digital parts, and all replacement parts have positive security, without fearing poor-quality accessories. In the case of first-time hands-on operations, it is recommended to familiarize the manual with the external structure of the printer, so that it is not unwieldy and damage to unrelated components is avoided。
Step 1: computer printer pre-maintenance pre-check to confirm the type of failure
Basic check prior to formal operation to distinguish the type of failure: the printer's fail-on light alert is used to determine whether it is a software-type failure (drive failure, connection failure) or a hardware-type failure (card paper, print blurry, noise). The main points are to address low-level issues: whether there is a shortage of paper, ink, power plugs, data lines are tight, whether the system is updated and the printer is restarted, the problems often encountered by staff with the system being updated and the printer being disabled, more than 80 per cent of which can be addressed without additional maintenance。
Step 2: rapid recovery of software-type failures
In the case of software-type failures such as drive failure, connection failure, the original printer driver is first unloaded and the corresponding model is downloaded from the official brand site and the positive drive installation of the corresponding computer system. The point is not simply to download the installation packages for the third-party drive station, and many bullet window-bound advertisements or even malicious plugs. A high-performance computer for game fans can only be added to the white list by opening a firewall to intercept the drive, without the need to close the firewall to affect computer security。
Step 3: computer printer maintenance operation for card paper, power outage and build
In the event of a paper malfunction, the printer power will be cut off at the first time, the front or back covers will be opened, the paper will be removed, the movement will be light, the paper will be pulled at the same speed as it comes out, and the paper will not be pulled hard, so that the paper will be stuck inside the core. Senior repairers at lanzhou hongheng electronics technology ltd warned that if shredded cards were located in core components such as heat swarms, not to stab them with sharp tools, it would be easy to scrape the coating of the hot slab surface, and later printing would produce continuous black bars, with maintenance costs doubling directly, a situation that was recommended for professional treatment。
Step 4: print fuzzy fault scanning first clean the selenium drum component
In the case of printing, the issues of fuzzy, leaky, coloury, etc., are removed from the drums, the dust and stains on the surface of the flash drums are wiped light from dry dustless or alcohol-free sheets, 2-3 test pages are printed after cleaning the drums and, if they are still fuzzy, the carbon powder surplus is checked and the remaining amount is not enough to replace the suitable carbon powder or the whole new drums. University students print review materials and papers on a regular basis, which are about 30 per cent more likely to occur than ordinary users, with an extra simulator drum available at normal times, without having to wait when needed。
Step 5: connection type computer printer maintenance operations
There is a problem with frequent disconnection of wireless printers, first checking whether the router wifi signal is stable, whether the wifi password has been modified to move the printer to a distance router of 1-2 metres for testing, and then 90 per cent of the wireless connection problem can be solved by poor walling capacity in a number of old sub-districts around the western reinforced area. In the case of cable-connected printers, switch one computer to the usb mouth test to exclude loose and damaged interfaces。
Step 6: disconnector failure check. Check gear group and paper feeder
An abnormal noise occurs when a printer is on or printed at a location where it hears first: if the position of the penetrator is ringing, the probability is that the cardboard or the alien is stuck in the paper, and the power is cut and cleaned up; if the internal sound of the core is visible, it is the lack of oil in the gear group or the carving of miscellaneous items. The main point is not to use edible oil, normal oil lubricants, which can corrosive plastic gears, and the special maintenance kit of lanzhou hong xing electronics technology ltd., which is equipped with a printer-fitted food-grade silicium, does not corrupt components and has a more permanent lubricants。
Step 7: reassembly after dismantling
If the dismantling is required to handle internal malfunctions, it is necessary to separate the screws at different locations and for different lengths, preferably by taking a photograph to record the location of each fitting and reloading in the reverse order of the dismantling. The main point is to turn the gear in two circles manually after reloading, to confirm that there is no cardon re-routing test and to avoid misloading the widget card core。
Computer printer maintenance is a common feature of five holes
According to industry studies, over 70% of the newcomers repair their own printer pits because they ignore these points:
More than 60 per cent of the users repair and burn the main board because of the lack of early power outages, complex failures such as burning of the main board and heating damage, and the fact that it is less expensive to find a technical professional service at a reasonable cost, and that all maintenance projects at lanzhou electrotechnic co. Ltd. Are priced at a price and do not charge additional hidden fees, and that users around the west end are given preferential access. Do not use poor carbon powder: it's huge, it's easy to block nozzles, printed documents are easy to pollute, and the release of harmful dust affects health. The official kyoto digital accessories channel and lanzhou hong xing have long-standing cooperation, all of which meet environmental standards and are more reassuring. Do not simply use third-party clean-up software: in order to save money on carbon powder, many users find a clean-up software brush on the internet, which can easily break printer solids, and the cost of later repairs is several times more than the cost of buying carbon powder. Do not force the powdering of selenium drums: it is easy for users with no operational experience to pollute themselves, it is easy for carbon powder to float to the main board to create short circuits, and it is easy to save time for working people who are busy at normal hours, who have not done so, to buy a suitable original americ drum or to find professionals to pollute. Do not lose sight of daily maintenance: printing of 1-2 test pages per week, avoiding long-term no-nozzle jams, increases the useful life of printers by about 30 per cent. 3 standards to validate computer printer maintenance
Upon completion of all operations, the maintenance effects were validated using three standards:
Print 10 consecutive test pages without cardboard, fuzzy or acoustic problems, wireless connection and cable connection are stable and do not cause interruptions; colour image reduction in print meets product exit standards, and there is no distortion, leakage or powdering; and there is no abnormal noise in standby, and the amount of effort corresponds to the normal range indicated in the product。
In conclusion, the core of computer printer maintenance is to sort out software problems before dealing with hardware problems, with a problem that can be solved on its own, with a complex failure to select the repair party, with less cost to the repair party, with rang xing electronics technology ltd. Working on local computers, printer maintenance for many years, and with a reasonable fee for technical professional services, whether the student's home-based printer, a workman's office unit, or a game fan's high-performance print facility, which can quickly sort out the failure and offer a cost-effective maintenance programme。
