Characteristics of UV flatbed printer
To most of the clients, non-UV printers are flatbed printers. At present, eco-solvent inks are generally used in printing. If too many prints apply eco-solvent inks, the material quality would be deteriorated, and the adhesiveness would be poor and need coating. Eco-solvent inks need to dry in the air because they are not easily dried, but can easily converge in winter. The advantage of eco-solvent inks is that their colors are better and brighter than UV inks.
UV printer: The inks dry as soon as they are printed. Most of the inks do not need to be coated, which spares a step in the process. Their adhesiveness are relatively stronger and do not weaken easily, but their colors are darker than eco-solvent inks, because UV inks dry as soon as they are printed, which is a very short time. The environment-friendly UV inks meet the needs of most productions and are the mainstream development trend in present day. 

FAQs about 10 malfunctions of the universal UV flatbed printer
1. The universal UV flatbed printer prints out blank papers
In the case of universal dot matrix flatbed printer, the reasons that the papers printed out blank mostly are dry ink ribbon, broken ink ribbon, damaged print head, etc. The solution is to change the ribbon or repair the print head in time. In the case of universal inkjet flatbed printer, the malfunction of blank prints is mainly due to jammed nozzle, empty ink cartridge, etc. The solution is to clean the nozzle or change the ink cartridge. In the case of universal laser flatbed printer, this kind of malfunction is probably caused by a developing roller without toner (a developing roller without DC bias); an ungrounded photosensitive drum that blocks the negative charges from reaching the ground; a laser beam that shows no effect on photosensitive drum a protective cover for selenium drum or s laser scan that is not open, etc. 
If the photosensitive drum of universal laser flatbed printer does not rotate, there will be no image generated and printed out on paper. Cut off he printers power source and take out the toner cartridge, open the selenium drums (toner cartridge) protective cover, leave a gel pen mark on the non-photosensitive parts at both ends of the photosensitive drum before installing it back to the printer. Open the printer to warm-up for a while, take out the toner cartridge and see if the marker have moved (to check whether the photosensitive drum is working properly). If the self-test papers are printed out blank, it should be checked that has the printer run out of toner, has the toner cartridge been installed properly, has the sealing tape been drawn out, has the laser scan cover been opened or blocked by foreign matters.

2. The papers printed out black
In the case of dot matrix printer, the reason of this malfunction can be ribbon depilation; overmuch ribbon ink; smudged print head; poor ribbon quality; the push rod that is too close, etc. First the position of push rod should be adjusted during repair. If the printer still malfunctions, change the ribbon and clean the print head normally work. In the case of inkjet printer, the focus should be on checking if the print head is damaged, if the ink tube is cracked, if the ink type is normal, if the ink pipeline is jammed, etc. In the case of laser printer, malfunctions are mostly caused by ineffective corona wire, or malfunctioning control circuit, selenium drums poor PCR conduction or neglected installation, making the laser fire all the time, OPC voltage unable to be discharged or charged, papers printed out black. Therefore, it should be checked that if the corona wire is disconnected, if the corona voltage is charged, if the beam detector in the laser beam access is working properly, if the selenium drums PCR is uninstalled.

3. Texts printed out incomplete or indistinct
In the case of universal inkjet flatbed printer, there may be two types of reasons: the toners are used up, or the printer has not been used for a long time, or the direct sunlight has dried the ink and jammed the nozzle. The printer needs to change a new cartridge or be injected with inks. If the cartridge is not used up or the nozzle is confirmed jammed, detach the nozzle and sink it in warm water for a while, prick it with a needle or shake it very hard. Be careful, do not sink its circuit board in the water, so as to avoid burning the printer.
In the case of universal dot matrix flatbed printer, this malfunction may be caused by overuse of printer ribbon; a print head that has not been cleaned for a long time; too much filth in the printer; pins broken inside print head; the print driver circuit malfunctions. The solution is to, first, adjust the distance between print head and print roller, if this malfunction still exists, try change a new ribbon. If it still does not work, you need to clean the print head. Cleaning method: remove 2 fixed screws on the print head, take out the print head, clean the filth on the print head with pins or hooks. And the filth are usually ribbon fibers accumulated in a long time. Then, drip some instrument oil on the back of the print head where you can see the pins, so as to clean off the filth. Print some blank self-test pages without installing the ribbon, then put back the ribbon. This way the problem can be solved. If this malfunction is caused by pins broken inside the print head or driver circuit, all you can do is change pins or driver tube.
In the case of universal laser flatbed printer, this malfunction may be caused by aging consumable parts; OPC/MR/PCR overuse or serious wear; TOER deterioration or contamination. Try change or renew toner cartridge. If the printers driver is incorrect or incompatible, or if the printer prints gibberish, etc. You can solve the problem by changing the data line or socket, closing the computer and printer before restarting them. 

4. The printer prints faint texts
In the case of universal dot matrix printer, this malfunction is mostly caused by dry ink ribbon; pins broken inside print head; a push rod too far positioned. The solution is to change ribbon and adjust push rod. In case of inkjet printer, this malfunction can be caused by jammed nozzle; dry ink; incorrect ink type; air in the ink tube; overhigh printer operation temperature. The solution is to test and repair the nozzle, ink cartridge and other parts. In the case of laser printer, faint texts may occur when the toner cartridge has too less toners; developing rollers developing voltage is low; toner has poor photosensitivity. The solution is to take out the toner cartridge and shake it lightly. If the print effect is still not improved, you should change the toner cartridge or adjust the set of photosensitive switches below toner cartridge. 

5. Texts printed out clear on one side and blurry on another side
This malfunction usually occurs in the case of dot matrix printer. It can also occur in the case of inkjet printer, but the possibility is low. The main reason of this malfunction is print heads guide rail and print roller being unparallel, and the gap between them are sometimes small and sometimes big. The solution is to adjust the distance between print heads guide rail and print roller. Method: unscrew the adjustment flaps on both sides of the print heads guide rail, twirl the flaps counterclockwise in order to shorten the distance, then adjust print heads guide rail and print roller to the level that they are parallel. Note that if the direction is right during adjustment, you can adjust them gradually after you print some texts and see the quality. This malfunction rarely occurs in the case of laser printer, and when occurs, it is usually caused by misplaced toner cartridge during changing, or the selenium drum that slightly blocks the scanning system. The solution is to change the parts. It is also possible that this malfunction is caused by DB/MR.
