You might notice tiny dots after transfer around the vector graphics, text, etc., which are not visible on the paper after printing, but only after transfer on the finished product, e.g., mug. The problem can also be diagnosed by careful examination of a test printout for the printer nozzle, where gaps of about 0.5-1 mm are visible between clusters of horizontal lines between vertical colours, e.g., 1 mm gap between LM and M and overlap between M and C. As there is no scientific explanation for this, the reason for the fault can be theorised based on the way of removing it. The colours that usually produce dust are Magenta, Light Magenta, and Black, and the problem usually appears in winter. We believe that at low temperatures or with worn out ink supply systems, the tubes become stiff and put too much resistance on the stepping motor, which moves the nozzle carrier and consequently the nozzle misses the proper place. When a printer prints around 6,000 dots per square inch, even the offset of LM dots of 0.5-1 mm will result in a blurred printout. Another reason are worn out supply cartridges or cartridges that are wider or narrower than they should be. This unbalances the nozzle carrier and prevents it from printing dots in the right places. Because the carrier is balanced for the original ink cartridge, installing a continuous ink supply system does not always bring the expected results. This is why it is important to choose the appropriate CISS for the printer while converting it to ensure correct balance. If dust generation is observed, the problem colours must be identified by the nozzle test printout, the respective cartridges in the supply system replaced, and the entire system vented.

Splashing drops of ink on the paper – caused by excessive pressure in the continuous ink supply system. To remove this fault, clean the head and then print 2-3 pages full colour at the highest quality setting. Repeat as needed until the printer stops splashing ink.
Vertical stripes (dots) on the printed page – this happens when sublimation ink does not dry quickly enough on the transfer paper. The cogwheel that guides the paper at the exit of the printer makes dots on the paper. It usually happens when coated paper of poor quality is used or when the room is cold and damp. There are three ways of dealing with the problem: 1 – using uncoated sublimation paper; 2 – placing a fan or a heater at the printer to speed up the drying; 3 – placing a plastic or rubber element on the guide, so that the cogwheels do not touch the paper (it is enough to raise the guide by 1-2 mm).
The printer does not feed paper – this can happen when the paper dispenser at the back of the printer, which moves the paper on the rolls that feed it to the printer, is blocked. In such case, it is usually enough to tap the dispenser lightly to unblock it. Another common reason is that either the paper or the rollers are too slippery. Anti-static spray or another product should be used on the rollers to increase their grip.
Printer error message saying that the internal parts of the printer are worn out or ink absorber needs to be replaced – this means that the internal counter of the printer shows a high value because of very frequent cleaning of the head or a large number of printed pages. You can look for a programme that can reset the counter online, e.g., at www.elektorda.pl, or have the counter reset at the Epson service centre.
The printer does not recognise ink cartridges – there are two possibilities. If the printer does not recognise only some colours, it is enough just to reset the continuous ink supply system with the reset button. If the printer does not recognise any colours, check that the cartridges are properly placed in the head, every cartridge has clicked in properly in the head, and that the power has been reset. If this does not help, the reset circuit has probably been damaged and needs to be replaced.

The printer shows a general error – there may be a number of reasons, the most common of which is jammed paper. In this case, make sure all paper has been removed from the printer and all trays are correctly installed. Then, turn the printer off and on again. If this does not work, contact us and we will help solve the problem.
Lack of one of the colours at the nozzle test or stripes and unnatural colours on the printouts – there are many possible reasons for this type of problem, but in general it means that one of the colours is not printing from the head. This is usually caused by a fault in the constant ink supply system. Because the problem can have so many causes, below is the procedure for diagnosis and repair that we use. Follow the guide or use the information to decide on the course of action yourself:
The printer prints double lines, e.g., vertical or horizontal vector graphics that are split – if the printer and the ink supply system are new, identify the faulty colour, replace the cartridge, and vent the system. If the printer is already partly worn out, do not set the highest quality printing option and the problem will disappear.
This is quite a broad subject and our customers often ask about it. As there are many opinions and myths about this particular subject, the subject is described here in detail. To begin with, if somebody is offering to sell you a sublimation printer or ink together with the colour profile, it must be a hoax and the only thing you will gain from it is a good feeling and the belief that you have a colour profile. When we sell a sublimation printer or sublimation ink, we do not provide a colour profile, but we do provide reliable information. Adding a general profile to a printer or ink makes no sense and is more likely to do harm than good. A proper and correct colour profile is made for a specific printer, not a model, because with small-format Epson printers at the lower end of the price range, no two printers are 100% identical. We noticed this while testing three sublimation printers at the same time. Three printers of the same model, with the same ink supply system and the same paper, perfectly vented, with perfect nozzle test results, new and working in the same atmospheric conditions, produced slightly different test printouts. We even noticed that each of these printers produced different sounds while printing. In addition to this, making a colour profile is a process where all variables, that is paper, ink, substrates, and their shade of white, as well as transfer temperature and time, must be clearly specified. What is more, the graphics software and the printer itself must be set up with appropriate values. It must be also mentioned that there are 4-, 5-, 6-, and 8-colour printers and each of them prints a bit differently, which is why providing general colour profiles makes no sense. We believe that much better effects can be achieved through using appropriate settings of the graphics programme and correct transfer, which together render 90% true colours. If you decide to use colour profiles, we currently have universal profiles for Epson P50 printers, made with our HQ ink, on our standard paper, and standard substrates. For this model, we have profiles for ceramics, ECO mouse pads, 100% polyester, and T-shirts with 50% polyester and 50% cotton content. These profiles can be made available on request by and can improve the quality of print, provided that the printer is working properly, uses fresh ink supplied by us, and you are printing on our materials and our paper. If you would like to have a colour profile made for your printer for a specific substrate, paper, ink, etc., we provide this service through our online shop. If you are buying a new printer from our shop and would like to receive a colour profile, you need to purchase this service through the online shop. The service takes around 2-3 days, together with converting the printer for sublimation printing and dispatch. We offer different colour profiles to suit your needs, made with 400, 600, 800, and even 1,000 readings. In special cases, we can adjust the profile to your needs, e.g., if you are printing billboards for Coca-Cola, where the predominant colour is red, you can order a basic profile extended red. In addition, e.g., the entire red spectrum can be defined, from 400 to 1,000 spectrometer readings. If you are printing billboards that will be illuminated, we can produce a profile that takes this into consideration to ensure the true colours of print under the conditions it will be displayed. We send profiles by , complete with the description of the conditions under which it was made and directions for applying it to the printer. If you would like to order a profile, a printer, and ink, paper, and substrates you are already using, this service is also available for you. You need to send the printer, in good working order, by courier. (PLEASE NOTE we do not accept responsibility for any damage to the printer in transport.) The printer should be supplied with fresh ink and print correctly. If we find the printer loses settings or is supplied with ink of very poor quality, we will not do a profile, as it would be pointless. When sending us a printer, also include paper on which the profile is to be made and specify the substrate, e.g., ceramics or satin.
The principles we follow when performing profiles are as follows:
Please be warned, there are companies that offer colour profiles based on printouts made by the customer from files sent by the company. A profile produced in this way is wrong in principle, not to mention the fact that it must be very narrow because of the small number of colour patches. We believe it is better to print without a profile but with well-adjusted settings of the printer and the graphics software than with an incorrect profile.
