EPSON STYLUS PHOTO 750 is a photo-grade color inkjet printer from Epson that features 1440dpi resolution, six-color printing, ultra-fine ink drops and smart drop conversion technology. I have been using this machine in the company and I have a good understanding of its "habits". Here I summarize some of the feelings of using it and discuss with you how to make better use of it for you.
Experience
1, the printer uses paper
In addition to plain paper, PHOTO 750 can also be loaded with special printing paper (photo paper, photo quality printing paper, photo quality inkjet paper, photo quality glossy film, photo quality film, inkjet transparencies, envelope cards). Wait).
Read the instructions carefully before using special media and note the following:
(1) Distinguishable printable surface: The printable surface usually has two different color differences to help determine the correct paper feed direction; for example, special photo paper, you can clearly see the color difference on both sides of the paper when you get it in your hand. One side is clearly reflective, and you should place this side up on the paper feed tray when printing. For some other printing media, please read the instructions carefully before use. There will be a clear method for identifying the printed surface. Please pay attention to avoid wasting paper.
(2) Paper quantity limitation: Usually, the special media printing has a paper quantity limit, and the paper overlap thickness should not exceed the rail mark on the printer.
(3) Other special requirements: Some media require padding on the underside, and some require adjustment of the position of the printer adjustment lever.
(4) Preservation method: When the printing paper is used up, it should be packed into the original packaging to avoid high temperature, humidity or direct sunlight.
2, the printing process
The EPSON Spool Manager is similar to the Windows Print Manager. When the printer has multiple tasks, it will be queued in the order in which it was received. When the print job reaches the end of the queue, the spool manager sends it to the printer.
3, printer storage
The contents of the printed file are stored in the TEMP temporary folder under the Windows directory of the computer, and several types of files with SJA, SBI, SBO, SPI, SPO, and PRN are generated. Except for the larger PRN file, the rest are several KB bytes. . EPSON PHOTO A 750 color inkjet printer typically stores only print content (one line of data) that is sufficient for the printhead to reciprocate once. Unlike laser printers, you can load a full page of print content from your own memory. Therefore, the finishing of the temporary space of the hard disk can optimize the printing speed.
Troubleshooting
The control panel indicators, combined operation buttons, supplied application tools, and EPSON Status Monitor 2 software of the PHOTO 750 printer can indicate the current status and error type information of the printer, and provide some common troubleshooting methods. When the printer has a problem, it can be solved by the above detection method. The following is a detailed description of some of the situations I have experienced.
Once, the EPSON PHOTO 750 color inkjet printer could not work normally. I could not find the fault by checking (the printer is normally switched, and the test page can be printed by operating the printer body control panel button, all normal), eliminating the printer's own hardware failure. . Suspected to be a driver problem, carefully checking the settings did not find an exception, but still reinstalled the driver. Several reinstallations and comparison instructions changed the settings and it didn't work. As long as the computer sends a print command online, it does not print (during the attempt to print a simple WordPad document, including printing through the test page on the printer's own software). After confirming that there is no problem in communication cable, software conflict, computer print interface, printer print interface, etc., check the printer monitoring software report installed on the computer is a communication error, the printer cannot be found. I also tried methods such as: refreshing the printer, enabling the printer's two-way support, changing the print port mode, etc., and I have not seen any results. I can't think of the cause. At this moment, I suddenly noticed that the black ink cartridge indicator on the printer control panel is always on, indicating that the monochrome ink cartridge is out of ink. After replacing one, try to refresh the printer again. The monitoring software indicates that the printer is ready, can be printed, and communication errors no longer occur.
This is because the EPSON PHOTO750 color inkjet printer is a six-color ink cartridge. It must be inked in six colors when printing. It has always been considered that black ink cartridges are not required for color printing (it is considered that black is dispensed by five colors, in principle) This is the case, but in order to appear pure black, you must have black participation, and the five colors can only be matched with brown), but it is not. It can be printed at the beginning of the direct operation of the printer to print the test page, because the black ink cartridge is only in the state of lack of ink, and the indicator light flashes. Later, the indicator light is always on, indicating that the black ink cartridge has no ink, but it does not care, resulting in printing failure.
The PHOTO750 printer cartridge status detection function is placed inside the body, and the detection alarm is completed by itself and the result is directly output to the printer control panel indicator. Therefore, when such problems occur, printer monitoring software can generally only symbolically suggest a type of error.
In addition, when there is a blank or light-colored area of the printout (cause the nozzle may be blocked), you can first check the test page by printing a test page containing six standard patterns. If it is inconsistent with the standard pattern, it can be cleaned. Print Head. This process is more expensive. During the cleaning process, it may happen that after one or two cleanings, the effect is not as good as before cleaning. I also have a way to clean the ink nozzle. I want to find a needle tube, use it to align the nozzle, and quickly pull the needle tube. At this time, the air will pass through the nozzle very quickly, and even a part of the ink will be sucked out, because the air flow rate is very high. High, can produce a better cleaning effect on the nozzle, but everyone should pay attention to master the scale when using this method, otherwise it will waste ink.
The above is my daily use and maintenance experience summarized in the use of EPSON PHOTO750 printer, and the experience of the front part of the article is also common to other EPSON printers. I would like to discuss with you.
