When the Cobas Integra 400 Plus encounters an operational anomaly, it flags specific numeric or alphabetical error codes. Below are common issues and their service resolutions. Error: "ISE Slope Out of Range" The potential difference generated by the Na+cap N a raised to the positive power K+cap K raised to the positive power Cl−cap C l raised to the negative power electrodes does not meet standard calibration curves.
Flush the waste manifold to prevent backflow and pressure errors. Semi-Annual and Annual Service (Engineers Only)
Replace the plungers and seals inside the sample and reagent metering syringes.

Solution: Access the optical assembly, clean the lenses with lint-free wipes, or replace the lamp assembly following the alignment guide in the manual.
Always wear gloves, lab coats, and safety goggles. Disposal: Dispose of cuvettes and tips as hazardous waste.
Holds up to 32 Cobas c pack reagents with onboard cooling. When the Cobas Integra 400 Plus encounters an
When a component is replaced or the system fails quality control (QC), precise alignment and calibration are mandatory. Mechanical Probe Alignment
Manually home the arm assembly. Use the service software interface to adjust the needle alignment so it drops precisely into the center of the sample tube, reagent cassette neck, and wash station.
Run a physical declogging wire through the probe needle. If the internal coating is compromised, replace the entire probe assembly and perform a fluidic pressure leak check. Error: "Temperature Out of Range" Flush the waste manifold to prevent backflow and
Unauthorized servicing or use of non-OEM (Original Equipment Manufacturer) parts can void instrument warranties and compromise patient results. Laboratories looking to train internal clinical engineers should contact their regional Roche Diagnostics representative to enroll in certified training programs that grant official access to software diagnostic keys and updated service documentation.
Run a cuvette blank check to measure optical clarity and identify scratched or stained cuvettes.
Houses the reagent rotor, sample rotor, cuvette rotor, and pipetting systems.
