particular failure or damage. “This is mainly referring that the Printhead has been used or currently used 

with expired ink or refilled or non-HP ink. Check within the current cartridge status.

Max Recovery Level: Number form 0 to 2. If set to 0, it means that there has never been any hard 

cleaning from the IPS done on this Printhead, to be checked before accepting the PH replacement in 

Warranty. When set to 1 or 2, it means that at least 1 hard cleaning has been done, but unfortunately, 

we do not have the information of when the last hard cleaning has been done. 

In the history part, the 

•

Yellow- Magenta (Serial Number starting by MY): correspond at the 2 previous replaced PH and the 

current one (upper line). 

•

LightMagenta-Light Cyan (Serial Number starting by NT): correspond at the 2 previous replaced PH 

and the current one (upper line out of the 3). 

•

Black – Cyan (Serial Number starting by KC: correspond at the 2 previous replaced PH and the 

current one (upper line out of the 3). 

There is less information within the history part, mainly the last status, error code, %age warranty used 

(100% = 12l, 260% -> 31l), Max Recovery Level and Usage time. 

In case if repeated issue, the column status and Error (ID) Code can give information of what is happening: 

STATUS: Both columns status are have a similar meaning, just the codification way is different: in the 

current, it is reported as OK, missing, …. 

Here is the conversion table: 

•

WORKING (=OK?) -> 0 

•

NO_PEN -> 1 

•

REPLACE -> 2 

•

RESEAT (=missing?) -> 4 

•

REMOVE -> 8 

•

REPLACEMENT INCOMPLETE -> 16 

•

TEST_SEPARATELY -> 32 

Error ID Code (=Error Code), is a decimal number and it has to be converted to a binary number 

before it can be used. In order to convert the decimal error code to a binary error code, you can use a 

calculator (you can use the one part of Windows, just need to select View -> Scientific to access the right 

functions). For example, if you had the error code 4099, you would enter 4099 as a decimal number 

and then select the binary option which would give you a binary number of 1000000000011. 

The following table explains the meaning of the different bits (0 or 1). When the value of the error code 

is reported as 0, it means that the Printhead is working correctly: 

The binary number needs to be read from right to left so that the 1st bit corresponds to the right one of 

the binary number. For example, the error code 4099 is converted to binary number 10000000000011. 

So using the table above, the error code means “FAILS_LOGICAL_V”, “FAILS_CONTINUITY” and 

“MISMATCH”.
