Power Switch Operation (ON/OFF)
The Canon P1-DHV utilizes a straightforward power switch for controlling the device’s operation. The On/Clear key also functions as the primary method for turning the calculator on, initiating all functionalities. To power the printer off, simply utilize the dedicated Power Off key, ensuring complete shutdown and conserving battery life when not in use.
Remember to always switch the power to the OFF position before connecting or disconnecting the AC adapter (AD-38) to prevent potential damage. Proper power management extends the lifespan of your P1-DHV and guarantees reliable performance. Consistent adherence to these simple steps ensures optimal usability.
Initial Setup and Paper Loading
Before first use, ensure the Canon P1-DHV is properly prepared for optimal printing. Begin by carefully inserting compatible paper rolls into the designated paper compartment, following the guides within the printer. The Paper Feed key is crucial for advancing the paper to the desired printing position.
Verify the paper is loaded correctly to prevent jams or misprints. Always use high-quality thermal paper for clear and lasting results. Proper paper loading is essential for consistent and reliable printing performance. Refer to the detailed diagrams in the full manual (available at the Canon support website) for visual guidance.
Understanding the Control Panel
The Canon P1-DHV features a user-friendly control panel for seamless operation. The On/Clear Key powers the device on and clears calculation entries – a single press clears the last value, while a double press clears all except memory. The Power Off Key safely shuts down the printer.
Utilize the Paper Feed Key to advance the paper for optimal printing alignment. The Non-Add Key prints non-calculation data like dates and serial numbers on the paper’s left side. Finally, the Print On/Off Key controls the printer function itself. Familiarizing yourself with these keys ensures efficient use.
On/Clear Key Functionality
The On/Clear key on the Canon P1-DHV serves a dual purpose, initiating power and managing calculation entries. Pressing this key once during a calculation clears the most recently entered value, allowing for quick corrections. A subsequent press clears all entered values, effectively resetting the display for a new calculation.
Importantly, this key also functions as an overflow error reset. If an overflow error occurs, pressing the On/Clear key will clear the error message, allowing you to continue operation. It’s a versatile key for both starting and maintaining accurate calculations.
Power Off Key Functionality
The Power Off key on your Canon P1-DHV printer is dedicated solely to turning the device off. This key provides a simple and direct method for conserving battery power when the calculator is not in use. It’s crucial to use this key when connecting or disconnecting the AC adapter to prevent potential damage or malfunctions.
Unlike the On/Clear key, the Power Off key has a singular function – complete shutdown. Ensuring the device is properly powered off extends its lifespan and prevents unintended calculations or printing. Always utilize this key for safe and efficient operation.
Paper Feed Key Operation
The Paper Feed key on the Canon P1-DHV printer is specifically designed for advancing the printing paper. This allows you to control the paper’s position and ensure printed information is placed correctly. A simple press of this key moves the paper forward, creating space for new calculations or printed data.
Utilize the Paper Feed key to manage your printouts effectively, avoiding overlapping or incomplete information. It’s a vital function for maintaining clear and organized records. Remember, this key only advances the paper; it does not initiate printing, that function is controlled separately.
Non-Add Key Usage
The Non-Add key on your Canon P1-DHV printer is a unique function allowing you to print information that doesn’t impact ongoing calculations. This is particularly useful for including dates, serial numbers, or other descriptive text alongside your numerical results.
When activated, figures printed via the Non-Add key appear on the left-hand side of the paper, clearly separating them from calculation outputs. This feature enhances record-keeping and provides context to your printed data. It’s a valuable tool for applications requiring detailed documentation beyond simple arithmetic.
Print On/Off Key Control
The Print On/Off key on the Canon P1-DHV provides direct control over the printer’s functionality, enabling or disabling printing as needed. This key is essential for conserving paper and controlling output during calculations or when reviewing results before committing them to print.

Activating the print function allows the printer to record each calculation or entered number onto the paper roll. Deactivating it prevents any further printing until re-enabled. This simple control ensures efficient paper usage and allows for selective printing of important data, streamlining your workflow and minimizing waste.

Printer Operation
The Canon P1-DHV efficiently prints calculations, dates, and serial numbers using the Non-Add key, offering versatile printing options for various applications.
Printing Calculations
Performing calculations with the Canon P1-DHV is straightforward. After entering your desired equation, the printer automatically outputs the result onto the thermal paper. Ensure the ‘Print On/Off’ key is activated for printing; otherwise, results will only display on the calculator screen. The printer utilizes the full width of the paper for clear, legible output.
To clear the last entered value during a calculation, press the ‘On/Clear’ key once. A second press clears all entered values, excluding those stored in memory. If an overflow error occurs during a complex calculation, utilize the ‘On/Clear’ key to reset the device and attempt the calculation again, potentially simplifying the equation. The P1-DHV is designed for efficient and accurate calculation printing.
Printing Dates and Serial Numbers (Non-Add Key)
The Canon P1-DHV’s ‘Non-Add’ key facilitates printing information unrelated to ongoing calculations, such as dates and serial numbers. Activating this key allows for the input of alphanumeric characters directly onto the thermal paper. These entries appear on the left-hand side of the paper, distinct from calculation results.
This feature is particularly useful for labeling, inventory management, or any application requiring non-mathematical printed data. Remember that utilizing the ‘Non-Add’ key does not affect the current calculation displayed on the calculator. It simply adds supplementary information to the printed output. Ensure the ‘Print On/Off’ key is enabled for successful printing of these entries.
Paper Handling and Maintenance
Proper paper handling and routine maintenance are crucial for ensuring the longevity and optimal performance of your Canon P1-DHV printer. Avoid exposing the calculator to direct sunlight or environments with rapid temperature fluctuations, high humidity, dust, or dirt. These conditions can damage internal components and affect print quality.
For cleaning, use a dry, soft cloth to wipe the calculator casing. Do not use water or detergents, as these can cause corrosion or damage. Regularly check the paper feed mechanism for obstructions. Proper storage and careful handling will contribute to a reliable and extended lifespan for your P1-DHV.
Avoiding Direct Sunlight and Extreme Conditions
To maintain the functionality of your Canon P1-DHV, it’s essential to protect it from harsh environmental factors. Direct sunlight can cause overheating and damage the LCD display and internal circuitry.
