(6) The printer is idle for too long
Fault phenomenon
◇ printer idle for a month without use, and now work is not normal.
◇ printer is not often printed, three months after the problem.
Solution
When your printer is idle for some time, the following three things may happen:
If the ink level of the external ink cartridge is lower than the horizontal level of the printhead, the air can be fed into the print cartridge from the printhead, since the return force of the ink in the ink supply line to the external ink cartridge is greater than the ink flow to the print cartridge, At this point the ink inside the print cartridge will have a small bubble, the ink in the tiny bubbles will cause the print disconnection.
◇ If the print head is returned to the initial position (the right side of the printer), the leak of the rubber gasket on the edge of the ink tank below the nozzle will also cause the adverse effects of the surrounding air on the printhead, causing the ink to dry and oxidize.
◇ If the printer is placed for a long time in high temperature, dry, direct sunlight environment, the same will cause the ink pipeline and print the ink in the nozzle to accelerate the evaporation, drying, bacteria and oxidation, for very thin and transparent ink pipeline Even more so.
The following are our effective measures to avoid these failures, please follow the order of steps:
◇ Before you prepare for a long time without using the printer, perform a nozzle check to ensure that the printed test leads are intact. It is best to print about 10 consecutive four-color or six-color block test chart (depending on your printer, the default settings to 360DPI print), and to ensure that the normal test results.
◇ Press and hold the cleaning button on the printer panel to give the cleaning command. Unplug the printer from the right side of the printer and start painting when the printer is performing cleaning (push the ink cart to the left, Use a soaked damp in hot water to gently scrub the rubber gasket on the rightmost side of the printer, which helps keep the seal clean and resilient, and then dries the cleaning guards into the ink tank. Sponge (drop full), and then manually push the ink back to the right side of the printer can be.
◇ observe the external ink cartridges color ink level of the highest height, raise the external ink cartridges so that the height of the printer and the nozzle to maintain the same level. Remember not to exceed the level of the nozzle! You can pad the book to keep this height.
◇ Finally, keep the printer and the continuous ink supply system in a cool, dark environment.
(7) installation failure
Fault phenomenon
◇ print in progress red light.
◇ ink in the printing process and the printer on both sides of the edge of the chassis friction.
◇ pipe on the back of the adhesive stick is not strong.
Solution
Ink line should not be too long. Adjust the length of the line from the pipe frame to the print cartridge to the optimum position.
◇ If the pipeline to the print cartridge ink pipeline length is too long, it will cause the ink pipeline in the printing and printer on both sides of the chassis friction. Should be taken back to the best length. Method is to perform the printing process to unplug the printer power, manually pull the car to the far left, and then to the far right, in order to ensure the printing of ink cartridges under the premise of this ink line to the shortest.
◇ If the length of the ink line to the print cartridge is too short, it will cause the red light to be printed. Should be adjusted in accordance with the previous steps to adjust to the best length.
◇ print process in the ink line and the printer on both sides of the edge of the friction situation occurred in the EPSON 780 /
790/810/820/830 /
C61 and other models, these models have a common characteristic: the upper part of the casing is curved on both sides. Although the use of finer and softer ink pipeline to avoid this friction, but the thin and soft ink pipeline is prone to blockage, ink and other phenomena, so do not meet the requirements of continuous ink supply system. Our ink lines have a high coefficient of friction, its toughness, strength and diameter are in full compliance with the international advanced continuous ink supply system design requirements. For such models, in order to weaken the ink pipeline and the edge of the friction, you can put the pipe frame on the right side of the printer, you can.
◇ pipe frame on the back adhesive is not strong, you can replace the new adhesive, and then paste.
(8) lubrication failure
Fault phenomenon
◇ print the ink truck hit the right side of the printer, while abnormal sound.
◇ The printer feeder does not work or the paper feed fails.
◇ The printer feed flashes and prompts "communication error".
◇ print position is not normal, left offset.
Solution
Similar problems arise mainly in the EPSON 700/780 /
1200 models, the cause of the malfunction is caused by the ink cart belt bounce, the lubrication of the truck spindle can solve this problem. With a paper towel dip LB-A lubricating oil on the main shaft, back and forth to push the ink so that the oil can be evenly coated on the shaft. Remember not to lubricate the oil droplets or spray on the spindle, not to let the oil dripping from the shaft.
Perform the following steps to eliminate the impact of ink and abnormal sound phenomenon:
◇ printer in the boot state, unplug the printer power plug, this time the car will be in the right position of the initial position.
◇ In the black ink cartridges corresponding to the bottom of the cart, there is a small white limit block. Can be found with a flashlight.
◇ with a tweezers to the white limit block forward (for their own) to dial down. Manually pull the cart from the initial position.
◇ At this time the power is still off the state, the ink truck pushed to the far left, until the push until the move.
◇ plug in the printer power, or turn on the printer's power switch.
At this point the printer ink stroke belt will bounce and reposition the initial position, the ink cart will eventually stop at the right of the printer's initial position.
(9) color failure
Fault phenomenon
◇ color document print out is black and white.
◇ print out the color and the original color compared to serious distortion or even the opposite.
Solution
Check if you are using B & W ink or print settings in black mode. If it is not, then perform a nozzle check, print test line to see, if the test line has a serious disconnection, please perform three cleaning orders, and then print the test line. After such a procedure, there are still serious disconnection after 3 times. Please use the troubleshooting method in "Bubble in Cartridge". If the test leads are normal, print a four-color or six-color block test chart (depending on your printer, print in 360DPI default settings). Compare with the standard patch test chart to check if the color sequence is wrong during assembly. Normal four-color machine color order: yellow (Y) → magenta (M) → cyan (C) → black (K). The normal six-color machine color order: yellow (Y) → light red (LM) → magenta (M) → light blue (LC) → cyan (C) → black (K). If it is determined that the color order is wrong, remove the ink supply line of the continuous ink supply system for thorough cleaning and replace the original original cartridge or empty cartridge.
(10) ink failure
Fault phenomenon
◇ continuous ink supply system in the initial installation or normal use for some time, the print test page is always one or several color disconnection, and other colors normal, repeated cleaning test results the same.
◇ found in the use of certain colors (relatively fixed color) often clogged the pipeline, plug the nozzle and disconnected.
◇ print color compared with the original color is large, or black is not black, or gray partial green, reddish.
◇ print portrait photos when the level is not enough delicate, not rich, there "wearing a headset" phenomenon.
◇ from the external ink cartridges can often see the sediment in the ink.
Solution
The above fault is caused by improper selection of ink, we recommend that you choose to provide you with all kinds of ink. EPSON is now compatible with the production of ink manufacturers, different quality, use different. In our labs, physical and chemical testing of thousands of ink combinations, high quality and stability of the ink is rare, and beyond the original EPSON ink performance or comparable with the combination is rare. Although you do not have to choose to achieve the image of the professional level of ink, but one thing should be noted that: continuous ink supply system should use the ink must be better than the ink used in compatible ink cartridges, and compatible ink cartridge must be better than bulk Ink with ink. In other words, the ink used to produce compatible cartridges is not necessarily suitable for continuous ink supply systems.
Many brands of ink are subject to strict physical and chemical analysis, a long period of stability testing, color is high, high density, good saturation, professional for the continuous ink system equipped with high-quality ink, you can ensure that the above does not appear bad.
If you only buy a continuous ink supply system accessories, but prefer to use their own selected ink, then you should at least from the following aspects of the basic test: 1, six months, the pipeline does not clog. 2, within three months the ink does not produce precipitation. 3, within a month will not dry knot, plug the nozzle. 4, 15 days does not produce serious dislocation. 5, within five days does not produce overnight disconnection. 6, the assembly is completed no more than three cleaning (including natural cleaning). 7, print color is only slightly color cast, black is. 8, gray is not green, not reddish. 9, print the head is not faint side.
(11) cleaning failure
Fault phenomenon
◇ print ink cartridge appears below the ink, the beginning of the print part of the print noise.
◇ When the cleaning command is executed, a strange sound is emitted.
◇ In case of no intervention, the printer sometimes executes the cleaning command automatically.
◇ The red light on the printer panel and the green light alternately flash.
Solution
Cleaning the nozzle command is to clear the print nozzle, excluding air bubbles containing ink, to ensure that the print effect and set, because EPSON for each printer are set to protect the ink counter, when the printer's cumulative inkjet volume reaches its maximum, the panel The red light on the power and the green light will flash alternately. At this point to the maintenance station to replace the printer inside the waste ink tray, and the ink protection counter cleared before they can work properly. So the use of the printer to try to avoid too much cleaning,
Cleaning too many times, out of the part of the ink will penetrate the bottom of the print cartridge, appear ink and affect the print quality. Some printers also emit a strange sound while cleaning. At this point should stop cleaning, with paper towels will be clean ink, put 30 minutes and then continue to work, the problem naturally eliminated.
Continuous ink supply system with permanent chip will increase the excess cleaning: shut down after 10 seconds to open the machine will automatically clean; interrupt the print command will automatically clean; sometimes in the absence of operational intervention will automatically clean the case. And the results of each cleaning will make the permanent chip count value is restored to full state. Therefore, in order to reduce the number of unnecessary cleaning, it is recommended not to use the permanent chip after the frequent switching power supply.
For ink protection counters, if you print a large amount, it is recommended that you use a set of 600 ml of ink each time after the clear maintenance, through the implementation of EPSON maintenance software can be achieved.
