Hi Everyone! just want to seek help regarding the error that keeps on appearing when I open my Hp T830 printer, 

It says error 026-0100, I already did my research and ity says that this error is for "Opto sensor" Can someone tell me how to fix this error and what should I do to prevent this from happening again...  I really appreciate your response!  Thank you!

System error: 0026-0100

Problem description: ISS Optotrip failure

Other potential parts associated: None

Corrective action:

1. Switch the power off and disconnect the power cord. Reconnect the power cord and power on the printer.

2. Go to Support Menu (The Support Menu for the customer is accessible from any screen by pressing the Power Button continuously for 15 seconds. Or by pressing "Back" four times.) and run the ISS diagnostic test.

3. Depending on the result, the call agent should arrange a service engineer visit to change the ISS.


In the best case there are just some ink on and around the opto sensors, wich are located in the Ink Supply Station (ISS), that might prevent their correct function.

In the worst case the ISS SV kit (F9A30-67008) need to be replaced.

How will I know that i need to replace the ISS already?
