Important note: Prior to changing from type G1 to type
G2 white ink – confirm that the nozzle check is good. If there are many missing nozzles, the process of changing over to type G2 ink will not necessarily resolve any preexisting clogging or other issue:
Please refer to this article on our knowledge base for tips on how to recover the nozzles. https://ricohdtg.com/support/ri-2000-head-recovery-guide

Loading White ink
When switching to the new Ricoh Type G2 ink there are a few things you need to consider when switching.
1. All cartridges must be switched at once . We can NOT have different white ink (Type G1 and G2) cartridges in the same machine. Print results will not be good and it may lead to nozzle loss. This means all white ink cartridges need to be matching.
2. Option 1 - It is recommended that you fully flush out the old type G1 white ink prior to loading the new type G2 white ink. – This will allow you to enjoy all the benefits of the new white ink right away. This means you will need Cleaning cartridges to flush the machine. You will need Full cleaning carts for W1 B and W2 B and at least 50% for the W1 A and W2 A to perform the twostep flushing process described later in this article.
3. Option 2 - You can also just perform just the 1st flush prior to refilling with White Type G2 ink which requires less cleaning fluid but does not fully flush the lines. Depending on the age of the printer or carriage this may be adequate.
4. Option 3 - You can also skip the flushing process and just put in the new Type G2 white ink cartridges. This will require at least 5 strong cleans on all 4 white heads to be performed after inserting the new
cartridges. This will not harm the machine, but you may notice nozzle
loss and will have to flush the lines at that point anyway.
Flushing the printer for Option 1 or Option 2
1. Check the level of the waste tank – if it is near full then you will need to empty it to prevent the flushing process from failing. In this case, make sure you empty your waste ink bottle and reset the counter.
6. Ri2000 – You have the option to flush the white carriage(WWWW), The CMYK carriage or both carriages. We will just flush the white carriage.
The flush process will take some time to complete.
7. The full Ri2000 printer flush will have two flushes for the white carriage.
The first flush will pull only a small amount of cleaning liquid into the tubes but will not clear the entire line of ink. If left in this state, the machine will still continue to perform head cleans in your white channels. This can be helpful when dealing with clogged nozzles. Eventually over time (days) the head cleans will clear the entire ink line and fill it with cleaning solution making the tubes fully transparent. In this state you can run head cleans and nozzle checks with cleaning fluid. Option 2 - You can refill with the new White type G2 ink after the 1st flush,
but you may not get the full benefit for some time.
Running Second flush Option 1 Recommended – Second flush is necessary if you
storing the machine and powering off, or switching inks The printer will allow you to perform the flush a second time, this second flush will fully flush the ink lines. After the second flush has been completed, your ink lines should now be clear. In this state the printer will not perform auto maintenance and will not allow to print nozzle checks.
#8 Visual inspection
After the flush has been completed check your ink lines visually to make sure they have flushed out completely. The white lines should be fully transparent when the 2nd flush is performed. If just the 1s t flush is performed, you will see some white ink or “milky” cleaning fluid inside.
White carriage lines should be fully clear after the 2nd flush. If you are just doing the initial flush, then the lines will still have milky appearance
