    "I then used your support service for the custom profile to see if it would improve things for me. Wow instantly there was a dramatic change. I wish I had used this service right from the start. Thank you for a great support particularly on a Sunday night when I least expected to be able to get support. For any other customer all I can say is not happy with your images get D.M. to run the printer profile for you. Itís well worth the effort."

  • Pierce foil on Magic Bullet and apply to both sides of cloth.
  • Lay the cloth under print head as video. Leave for a few hours, the vapour from Magic Bullet will soften the dried ink residue.
  • Take out the cloth and print color prints or purge flles included with the magic bullet kit. Repeat this process until you acheive a perfect nozzle check.

Included with all Magic Bullet purchases is our "Essential Printer Maintenance Video" compatible with Mac and PCs. This video has thirteen videos with seven printer cleaning areas. The areas of printer maintenance/recovery included are:

Inkjet Printing Best Practice
The number one rule: Use your printer regularly!

As well as using your inkjet printer as often as you can, it is a good idea to print a nozzle check before each printing session. A complete nozzle check ensures that all nozzles are working your images should print with no banding and accurate colors.

If your nozzle check is not complete, the most likely cause of this is that you have run out of ink or your printer's head requires a clean. Once you have either topped up your ink or carried out a head clean, print another nozzle check to ensure your printer is functioning correctly.

With inkjet printing problem prevention is definitely better than problem solving. During periods of non-use, turn your printer on for a few minutes once every 2-3 days. When you turn a printer on, it goes through a mini priming-cycle, which keeps the underside of your printer moist and can prevent the build up of dried ink on the underside of your ink head.

If you go on vacation, why not leave your printer switched 'on' and connect your printer to the mains through an inexpensive timer switch, set to turn on for a few minutes every other day - when you return, your print head will be in perfect order, ready to print.

Here are two general maintenance videos for large format printers. We suggest the video on the right should be followed at least once a year to maintain key functions of your printer.

Fine Art and Matt Papers = Off (No color adjustment)

Fault-Finding Your Printer
When you notice something is wrong, do not panic! Read on...

It is important not to fear the worst when a blockage occurs. It is vital that you select the correct cleaning method and to not "over clean"!
Generally, print workers discover a printer blockage when they observe banding or a lack of "punch" in their prints.
Once a less than perfect print is produced, you should follow these troubleshooting techniques:

If you are using single use cartridges, check your status monitor (located in your printer driver). This is only a rough guide and often the printer fails to alert you of a low cartridge ink level.
If you are using refillable cartridges, top these up to 90% full and if you are using a continuous ink system, ensure your ink reservoirs are at least two-thirds full.

Ensure that you have the correct print resolution (usually "Best Photo" or "Level 4") and that you have the correct media type for your inkjet paper.
If you are still experiencing poor prints after you have confirmed your ink levels and printer settings, you will then need to find out how your individual printer nozzles are performing:

A perfect nozzle check should include as many complete sections as you have cartridges in your printer, appear uniformly staggered with clear and crisp text underneath. This is printed from your Printer Utilities section in your printer driver.

Here is how to print a nozzle check to test for clogged inkjets
- If you are using a PC, access the Windows Desktop and right-click the product icon in the Windows taskbar.
- Using a Mac, select System Preferences from the Apple logo on the top left of your screen. Select Print & Fax, Print & Scan, or Printers & Scanners and then select your printer. Then its Options and Supplies. Select Utility and select Open Printer Utility to print the Nozzle check.

Perfect Epson Printer Nozzle Check

Incomplete Epson Printer Nozzle Check


If your nozzle check is incomplete (as in the right image), use the "Clean" function in your printer utility. This may take a few minutes to complete. Once the clean has finished, print another nozzle check to discover how well this has worked. If the nozzle check is now complete (as the left image) you can now start printing. If the nozzle check is still incomplete, carry out no more than 2 head cleans.

In the more up to date printers, there is also an "Automatic Nozzle Check and Head Clean". This is a more intense cleaning cycle so we only recommend this if your nozzle check is less than 50% complete.

In very rare cases, if your nozzles are not uniformly staggered, you can correct this using the Auto Head alignment. (Performed in printer drivers utility).

In our experience, if your nozzle check is missing in the same place each time, the print head itself is at fault and the likely cause is ink that has dried outside the print head. If your nozzle check is variable, the likely cause is that air is entering the ink system, usually due to the cartridge failing to make an air-tight seal with the printer. Although often air can enter through internal splits in the ink lines, damper or connections. So if you have a variable nozzle check, we advise changing the suspect cartridge(s). If your nozzle check is missing in the same places each time, read on...

If your Inkjet printer has become clogged (obstructed with dried ink), the ink in and around the printer head would have hardened due to a combination of air, paper dust and, most often, lack of use. In this instance, we recommend using a combination of Magic Bullet Print head Cleaner and printing purge files to remove the blockage and get your ink flowing freely again.

Magic Bullet fluid is used by experienced printer technicians typically using several maintenance/restore techniques with good results, and can clear even the most stubborn blockages.
The printer purge files aid the flushing process and are included with the magic bullet purchase. Click Here to view the printer head cleaning video and for the Magic Bullet purchasing details.

ICC Profiles and Color Management
Basic set up and printing for the most critical photographer

Marrutt Photographic Pro Inks are formulated to provide a very close match to the original OEM ink set.

For normal-basic printing you can simply use the normal Epson print settings. This will provide a good standard accuracy in colour and black & white with correct print density (plug and play).

This is particularly useful when printing from non-Adobe Photoshop applications, which do not support colour management.

For more critical photographic applications, you can use the recommended Epson generic Profile for your printer / paper combination. We are also able to provide custom profiles to provide an improved level of color accuracy, tonality, density and shadow detail. Please contact us for details of this service. In addition, we supply free a calibration print and checking image JPEG to confirm that your printer stays accurate for colour, density and neutrals.

Epson Stylus Pro 7700 Purge Files
Clear a blocked printer head without using the cleaning cycle

Printer purge files are areas of a solid color (or a selection of colors) that can get clear a blocked printer without having to resort to printer cleaning cycles. For more severe blockages (where your nozzle check is missing in the same places each time), we recommend you carry out a combination of printing purge files (individual or complete depending on the color(s) that are missing) with cleaning the printer using the Magic Bullet cleaning fluid explained below. This combination means you are softening the ink that has dried inside your printer using the Magic Bullet fluid and then pushing the ink through using the purge file.
Please find below the complete Purge file for this printer as well as the individual purge files that you can download for printing.
