The ROLAND InlineInspector is an optional sheet inspection system for the ROLAND 700 printing machine, designed to detect faults on freshly printed sheets during their travel through the last printing module. This system helps to ensure print quality by identifying errors such as dirt, scratches, creases, streaks in the printing material, or fluctuations in the printing process.

Function Description:

The core function of the ROLAND InlineInspector is to scan each printed sheet line by line on the impression cylinder using a camera (1). The data captured by the camera from the freshly printed sheet (2) is then compared in a computer with pre-established reference sheet data. If any deviations are detected, the system triggers a warning signal, and the identified errors are displayed and logged on a screen (4). This immediate feedback allows the printer to analyze and eliminate faults caused by the printing process without delay.

For handling faulty sheets, the system offers several features:

• Marking: Faulty printed sheets are marked with a stripe in the delivery section.
• Ejection (Optional): An optional sheet ejector can immediately remove faulty sheets from the production line.
• Numbering (ROLAND InlineNumbering option): When combined with the ROLAND InlineNumbering option, sheets can be numbered consecutively. In the error log, these numbered sheets are then assigned to their respective errors, providing a clear record for quality control and analysis.

The system's operation is managed through a central control console (4), which includes a dedicated switch cabinet for the sheet inspection system (1 on page 9). The software operation of the sheet inspection system is detailed in the manufacturer's instruction manual.

Important Technical Specifications:

• Product: ROLAND InlineInspector
• Series: ROLAND 700 (specifically 778)
• Construction Year: 2021
• Language of Manual: EN - English (original manual in German)
• Publication Status: 08.03.2021
• Target Group: Owner-user of a printing shop, operating personnel (Helper – Skilled worker: printing machine operator).

Usage Features:

• Central Control Console: The system is controlled via a central console, which houses the switch cabinet for the sheet inspection system.
• Main Switch: A main switch is provided for the sheet inspection system, primarily for emergency cut-off. Actuating this switch causes an immediate standstill of the sheet inspection system without data backup and should only be used in emergencies to prevent damage to installed software and data. Only specially trained and authorized personnel from manroland or their sales/service partners are permitted to actuate the main switch for routine operations. The main switch must always be in the "ON" position during normal operation.
• Software Operation: Detailed instructions for operating the software are found in the manufacturer's instruction manual.
• PDF Creation: The manual refers to PDF specifications and checklists for creating PDFs, which are essential for the system's operation, as outlined in the Manufacturer's Operating Instructions.
• False Alarms: The system may occasionally generate typical false alarms due to misinterpretation.
  • Unsuitable Reference Sheet: If a high number of faults are signaled at the start of inspection, it often indicates an unsuitable reference sheet. A new reference sheet should be read in.
  • Sheet Tail Edge Fault: When printing cardboard (from 130 N/mm), the sheet tail edge might lift off the impression cylinder. This can be addressed by redefining the inspection area to ignore this lift-off.
• Clocked Blast Air: The blast air system prevents the deflection of the sheet tail edge onto the baffle plate or inspection lamp and the formation of corrugation with thin printing materials (<150 g/m²). The blast air can be adjusted using a rotary button: turning left increases blast air, turning right decreases it, and turning it fully to the right (up to the stop) switches it off.
• Cardboard Printing: For cardboard printing, various elements can be removed to improve printing results. These include the baffle plate with blast tube and the sheet guiding element. Specific inspection and ICP restrictions apply when these elements are removed, particularly concerning UV intermediate dryers and printing material thickness. The inspection lamp must be switched off when the baffle plate with blast tube is removed for printing material <150 g/m² or for inspection.
• Removing Sheet Guiding Element: This element can be removed, especially if manual washing of the impression cylinder is required. This task should always be performed by two people due to the risk of personal injury. The procedure involves locking the printing machine with the 'Stop-Safe' key, opening guard 9.8, folding open the retaining frame, pulling out the locking mechanism, and then pulling the sheet guiding element out evenly and parallel to the machine. Installation is the reverse process.
• Removing Baffle Plate: The baffle plate can also be removed to improve printing results, particularly for cardboard. This task also recommends two people and requires a socket wrench (width across flats 10). The process involves turning a threaded spindle and removing the UV-dryer protective housing.

Maintenance Features:

The manual provides a maintenance schedule with tasks not dependent on operating hours, categorized for different intervals:

• Weekly Maintenance:
  • Cleaning the LED lamp (Page 11)
• Monthly Maintenance:
  • Cleaning the outside of the glass pane of the camera housing (Page 12)

Cleaning Procedures:

• Cleaning the LED Lamp: Requires a lint-free cloth. The procedure involves locking the printing machine with the 'Stop-Safe' key, opening guard 9.8 over the impression cylinder, and then cleaning the LED lamp. If the LED lamp's output decreases, contact manroland sales/service.
• Cleaning the Outside of the Glass Pane of the Camera Housing: Also requires a lint-free cloth. The procedure involves locking the printing machine with the 'Stop-Safe' key, opening guard 9.8 over the impression cylinder, and then cleaning the glass pane.

Delivery/Installation/Removal of Strip Inserting Device:

• Removing: Involves locking the printing machine with the 'Stop-Safe' key, opening guard 40 in front of the sheet removal zone, pulling off both connectors (1) from the device, and carefully lifting the strip inserting device (2) out of the delivery.
• Installing: Involves locking the printing machine with the 'Stop-Safe' key, opening guard 40, carefully lifting the strip inserting device (1) onto the fixing plate until it engages, and connecting the two connectors (2).
