White Toner Refills and Chips for Oki

Oki white toner printers are used for specialist printing onto textiles such as T-shirts. A white background is necessary for colours to show brightly on dark garments. The Oki C711WT, ES/Pro7411WT, C920WT, Pro/ES9420WT, C941dn and Pro9541dn are specially designed to print colour on top of a white background. The finished transfer paper is then hot pressed onto the garment. It can also be used for printing onto other dark items such as mugs and leather jackets. The original Oki white cartridges are very expensive to buy and a significant saving is possible by refilling them.

Original White toner for Oki

We supply white toner in an 800 gram bag. This is the original Oki OEM white toner. It gives excellent results for professional white printing, the same as a new original cartridge. It is compatible with all Oki and Intec white models including the C711WT, Pro/ES7411WT, C920WT, ES/Pro9420WT, C941 ,Pro9541/9543 and Pro8432WT printers. White toner is more expensive to manufacture than the regular colours, and this is reflected in the higher price. With our bags it is still possible to make a significant saving over the original cartridges with no difference in print quality.

Our original white toner bag for Oki gives professional quality results.


January 2023: This product is now back in stock. It's only available in 800 gram foil bag packaging. Following a shortage of supply and without stock from August 2021, we are pleased to supply it again. The price per gram has increased by 27%. This is due to higher cost price, poor US dollar exchange rate and higher shipping costs.
Reset Chips

The cartridges have a killer chip. This is designed to stop refilling and locks out the cartridge when the supply gets low. It is necessary to replace the chip each time you refill to reset the cartridge. With the new replacement chip the cartridge shows 100% full and can be used for another lifetime without interruptions or warning messages.

We are pleased to make available the first aftermarket replacement white chips. You may order in quantities ranging from a single piece upwards. By purchasing only the quantity you need you will always be ready to refill with minimal cost when the dreaded replace cartridge warning appears.

We stock the chips for many white models including the C711WT, ES/Pro7411WT , ES/Pro9420WT , C941 and Pro9541dn.

Conversion of Normal Printers

The toner we supply is universal to many regular printer models. This enables conversion of normal printers to white. It can be a good low cost alternative to investing in a specialist printer.

Colour Printer

The bottle is universal with many regular Oki colour printer models. It is possible to clean the colour from a standard colour cartridge and convert it by refilling. The key is to remove as much of the residual colour as possible to avoid contamination of the new white. It is also necessary to remove the residual colour from the imaging drum cartridge. One way to do this is to keep printing with an empty drum until very little comes out onto the page.

There are two ways to make a converted printer:

1. White or Colour -Prints in separate passes or using two printers. A machine converted in this way is not as versatile as a specialist CMYW machine that can produce bright colours on a white background in one pass.

With a converted printer it is possible to make the white background seperately. The colour graphics can be printed on the same transfer paper using a regular colour printer first. Our customer in Indonesia, Kaoskus, has done this and prints professional T-shirts using an Oki C332dn converted to print in double white (using M & Y). The colour graphics are printed using a regular C332dn. Because the two printers are the same type, the registration of the colour onto the background is acceptable.

Kaoskus now has also converted an HP Color LaserJet Pro M254 to trans white. It is possible to use just one printer by having two sets of cartridges - one for the colour print and one for the white print. He does the colour pass first, then swaps to the white cartridges and prints again to layer the background ontop.

2. Single Pass CMYW
A better way is to fully convert a normal colour printer so that it prints colour graphics onto a white background in one pass. This is just as good as having a specialist model.

To do this you must change the orders of the colours. The standard order is KCMY (or KYMC for some recent Oki models). It must be set to CMYW (or CYMW) so that the white background is layered ontop of the colour graphics as the final stage in the printing process.

Specialist RIP software is available that works with all PostScript models. This software lets you change the order of the colours in this way.

You will need a PostScript printer that lets you install the drums in different positions - ie. it does not detect any difference between the drum for each colour. It lets you to change the colour order without throwing an error.

Many Oki models are suitable for this conversion. It has been successfully carried out on a C830. Oki printers also have the advantage of a straight through paper pass, allowing use of heavy media and card stocks.

There is a Korean company that supplies a single pass conversion kit for the Oki C610,C612,C831 and C822 models. This includes their own "Freestyle RIP" software. They can also supply pre-filled drums, and fully converted printers.

Monochrome Printer

A lower cost alternative is to convert a monochrome printer. The bottle is compatible with the Samsung ML-1610, Oki B411/431 and Xerox Docuprint P105/205 monochrome machines. It is also universal with many other Samsung monochrome printer models. These are low cost machines and easy to refill. It is possible to convert the black cartridge by cleaning out all the residual black and refilling. One way to do this is to vacuum out the empty cartridge, and then print until very little black comes out onto the page.

A converted monochrome printer is useful for specialist applications, such as printing onto black paper or card. This can be used for restaurant menus and graphic art.
It is also possible to print the background onto transfer paper using a converted monochrome printer, for printing onto dark clothing. The main complication is that you need to use computer software to separate the background from the colour graphics, so they can be printed separately. It is not as versatile as a specialist CMYW machine that can produce bright colours on a dark background in one pass, and comes with the specialist software and drivers included.

Refilling other Specialist Models

Various other manufacturers have released special printers for textiles. These include HumanWare, Uninet, U-Print and SunAngel Imaging. The Oki toner we supply has not been specifically qualified for these machines. However we believe that the toner formulation is similar. It is most likely that you can refill these cartridges and make a significant saving over the original supplies.
